for those with EFI...show me your wiring....

[turbobrat930]

I would like to see how you guys have routed your wiring, placed and mounted your computer, relays, etc... I will be wiring mine this weekend...hopefully if the unit shows up. I already have an idea what I am going to do, but would like to see some pictures of how others have done it... Thanks Brad

I don't have any pics of my EFI wiring on this computer, I'll look when I get home. I used a 47 pin Duetsch bulk head connector through the rear bulkhead behind the rear passenger side seat. I installed the ECU under the passenger seat. My ECU relay is in the front trunk by the fuse box and I used the stock fuel pump relays.

Here's a pic of the new and old engine harnesses (no EFI wiring in this harness). I was able to eliminate a few wires .

Hey, david, thanks for the reply. I will be doing that to my engine harness this afternoon. It is amazing what you can get rid of, since we don't have CIS.

I was actually looking for pics of say, a group of relays, or the EFI control box itself and how it is displayed with all of the associated wiring. I was thinking of getting a piece of aluminum, and mounting everything to it, routing all of the wires in a neat fashion. Just wanted to see how everyone else out there has theirs mounted...wanted to get some ideas... Thanks for the pic... do you have any more? Brad

Here's a pic of the installed engine. The bulk head connector is near the top middle of the pic. I haven't put on the shrink wrap so you can vaguely see the 47 wires going into it. A picture of my relays wouldn't show much since I used the stock fuel pump relays and my ECU relay is just laying near the fuse box.

I got some brackets for my ECU that bolt to the floor board and my BAP sensor is next to it on a simple aluminum bracket.
I need to pull the seat again since I forgot to write down my ECU serial # , so I'll snap a pic then.

The O rings are there from the factory. They help seal the joint between the I/C and the TB. If you didnt have them, there would be boost leaking between the two metal joints....

damn, David, that looks very nice... I would be interested to see your pic under the seat... thanks....

Actually, I didn't know what was in that groove from the factory, but it looked like two orings would fill the groove nicely so that's what I used .

Mine had one thick orange o ring in it from the factory... but if two smaller ones do the trick...then cool

the 3.2 intake TB never had orings as the groove was for the afm boot to "seat "against

Here's my ECU and BAP: (that flash sure makes the carpet dust show up )

Does anyone have a factory diagram for 77 930 ROW car? It would be a great deal of help for the stage I am in with my EFI conversion.

Thanks and sorry for thread robbing but it was fairly on topic.
