Engine compartment wiring/routing
 

Hello all,

I'm new to this board. I have a 1986 Non turbo 944. I am changing the color and having a rebuilt motor installed. My mechanic is awall. Its been several months since he has worked on it and I cant get him back on the project. I have the body and paint mostly done, but now I have to complete the motor swap my self. The motors in, but I'm having a hard time figuring the wire routing, some connectors, and most of the vacuum lines, Motor ground, etc.. Would anyone know where I could get a manual complete with pictures, or any suggestions? I live in PA, and my car is in Maryland, dont ask.http://forums.pelicanparts.com/uploa...1133072852.jpg http://forums.pelicanparts.com/uploa...1133072887.jpg

OUCH.....

Ok guys, post some photos for the man. I don't have a 44 anymore, so I can't.

Do you have a copy of the workshop manual?

AFJ

Ouch.

Seeing as how it is taboo to post links to copyright material (as in the workshop manual), my advice would be to check your private messages.

Thanks for the call out and help guys. I got some stuff to keep my busy for awhile.

Whats funny is mine looks like that right now...........

Having done this a few times now......... I am getting quite intimate with these cars..........


Things I see from your pic...

1. On the passenger side over by the light bucket...

- The grounds on both sides bolt up to rail. I can see them dangling. (brown wires)
- coil wires
- 2 sets of wires for washer fluid motors (you have two little motors)
- Plug for the pop up light mechanism
- You should have a head light plug and a fog light plug and side marker and turn light

2. drivers side bucket
- you have a ground by the rail as well (bunch of brown wires)
- you have 2 wires for AC
- you have plug for headlight and fog light and turn light and side markers

3. At the firewall you have the engine grounds but we are not there yet.....

P.S You should of sprayed the booster BLACK while you had it out.....

but otherwise its looking nice and shiny.

Thanks Ae1969, #1 I have coverd as I removed them for paint. The A/C isnt hooked up yet, and I'll check the firewall grounds. Where does the Engine ground bolt to? The one coming from the battery?

Here's where I am now.http://forums.pelicanparts.com/uploa...1133257980.jpg http://forums.pelicanparts.com/uploa...1133258441.jpg

looking good! nice fenders n bumper ;)

Thanks, not going to paint fenders or hang bumper till I'm done hanging over them. BTW, I bought used nose to make it look tike a turbo.http://forums.pelicanparts.com/uploa...1133433940.jpg The car is not mine until I've taken it apart and put it back together. Changed the interior to all black as well. http://forums.pelicanparts.com/uploa...1133434353.jpg http://forums.pelicanparts.com/uploa...1133434580.jpg

I like it.. especially in black! makes my turbo skin look shamefull....

Looking good........

You have 2 grounds from the battery.........

- Behind the battery in the fire wall its an M8x35
- On the back of the bell housing it should be a M8 stud

I'm still working on it. All electrcal connections have been made. A couple of vac and air lines to route. What is the proper firing order, and is there a fuel cut-off switch on these cars?

Nevermind on the firing order, I just had to open my Eyes.

I don't know of a fuel cutoff switch. The DME relay turns the fuel pump on ONLY after you start cranking the car. If the flywheel isn't turning, the fuel pump isn't pumping.

Do a search on here for vacuum line routing...it's been posted over and over.

Where are you at in Pa.???. I have the factory workshop books, and several 944's sitting around. I am north of Pgh. I am sure I can be of some help, I have just swapped two motors in the last couple of months, and Most of it is still fresh in my mind

I'm just outside of Philladelphia. I have the Vac lines routed, and the electrial connections done. Checked the fuel pump and it works. Bypassed the DME relay heard pump, cranked but no start. Have to check the spark next. I was hoping there was an easy button, but no luck. I'ts been a long haul, and I deperately want to get it back on the road. I sure I'm overlooking something simple but I dont know what.

Heres where I'm at now, Have to track down why it wont start.

That was an incredble amount of work. One thing I have learned from this post...if you want to change colors...sell the one you have and buy one the right color. Do you have spark?

Ran out of time, haven't confirmed spark or not. Next chance to work on it is Oct 28th (car's in Maryland 170 miles away, long story). Mean time any thoughts would be appreciated. BTW, I drained tank and put fresh fuel when I checked the pump.

Hello gang, I need your prayers this weekend, Hope to get it started finally. One question I'm trying to rule out does the 86 non turbo have a speed and reference sensor? Been checking out some of the posts and it seems to be something I need to rule out, (if I have one). Dont remember seeing one.

I'm sure it does. My 87 NA does, and they didn't do a whole lot on the NAs from 86 to 86.

Where did you get your interior pieces? it looks great! My turbo needs some new interior...

It's almost shameful

Thanks, I'll check the sensor this weekend. Carpet and door panels from e-bay, Seats dash and console from www.germanautodismantlers.com. Some trim pieces and switches from Pelican Parts and 944online, Mechanical stuff also.

Yes, they have them. They are on the left side of the car right behind the engine. They will be directly above the flywheel. They come up to two connectors pretty close to the hot water valve of the motor.

Were the door panels from a stripped car?
If so you got very lucky!

Yes they were, got lucky on the dash also, minimal warpping near the top vents, thanks

We'll No spark for sure, Going to check coil. Swapped DME relay, Cheack for fuel at the rail, Havent checked power to FI yet but I'll do that after I check coil (I bought a spark tester and checked uoutput, no spark at all). Found the speed and position sensor, they were connected, but seems both have the same connectors so you are able to conect one to the other, any way to tell which one is which?

Probably not the coil...they don't go bad real often. Do a search for a post by a guy called SoCal Driver and search for "five minute test" ...that will tell you step by step what to do to find the problem. If you think the wires are swapped, switch them and see if that makes a difference. I'll try looking in my book to see which is which as I don't remember off the top of my head. Anyone else know?

Thanks for the tips. Still no start. Have the Speed and reference sensor wired right (One of them was marked on both ends). Cant confirm the five minute test because 2 weeks ago I had the Speed and reference wires connected wrong (but didn't know it), I took the DME relay out and did the jump test from Clark's garage, the pump was working, I then set the DME aside and used one from an 83, different part# but it fit, still nothing. Fast forward to this weekend, Checked for fuel at the rail while cranking engine, Not scientific but it filled a gallon can pretty quick. Took another look at the Speed and reference sensor wires and noticed they were connected wrong, swapped them correctly, still no start. Although I swear I heard a moment where is seemed to fire, probably my imagination. Went looking for the original DME but couldn't find it. Am ordering a new one today. Hopefully there is enough difference between the 83 and 87 DME to make the difference, or that the 83 DME was bad. Keep the tips coming please. Maybe connected to this problem but probably not, while I was checking wires I noticed under the dash a connector that was wire tied to the rest of the wire loom. Is this for an accessory I don't have? Does anyone know what this might go to, maybe my easy button (fat chance).

TIA

Definitely a big difference between DME's. If you have the right one, that will make a difference...just not sure how much. That connector looks like it connects to a switch...maybe one on the console although I don't know which one. Check the switches on the console to see if one is not connected. Check the colors of the wires going to it and then look at the electrical diagrams on this site..maybe that will give you some indication.

The good part about the gas check is that you know that circuit in the DME relay is working which is also telling you the speed sensor should be working as I think that controls the DME relay to tell it the fuel pump should be pumping. Time to get back to tracing why you don't have spark.

Yeah small steps right. Will be working on it again in 2 weeks.:confused:

Well put the new DME relay in, still no start. Good news, I trailered it back to PA from Maryland, so now my baby is minutes away. My buddy let me put it in his garage next to his Turbo. maybe they could talk at night. http://forums.pelicanparts.com/uploa...1165320396.jpg http://forums.pelicanparts.com/uploa...1165320421.jpg
Just to recap: Doing a near ground up restoration, Bodywork complete, Interior back in. Every circuit works, except for door locks, and rear wiper (track them down later). Had someone remove engine and install rebuilt motor. He got to dropping motor in and then was not available to finish. I picked it up from there. Got all the wires and hoses connected. Here's what I know, Fuel pump works and flows when engine is cranking. I assume the speed sensor is working. What does the reference sensor do? Need to verify if getting spark, and power to injectors (new injectors). Will try this weekend. Step by Step check sequence would be apreciated. Any poster live near Springfield, Delaware County?
