78' 3.0 engine wiring issue
 

I am currently installing a 3.0 carrera engine from 78' in my 71' 911. The engine is in place and i am wondering if anyone has a diagram for the wiring harness that ends with the 14pin plug. ( for all connectors on the harness ). I have searched the web without luck.

Also, i assume i do not have a ignition control unit that works with this engine. Is an original one easier to install or should i go for one of theese

If anyone have links to threads by people doing a similar engine swap i would be glad to get them :)

Best regards
Roger

Here is a picture of the wires, i would believe maybe nr 1 goes to the fuel pump? and number 3 to the ignition control unit. But do someone know for sure, that will help me a lot :)

I'll take a shot at your plugs. No. 3 is definitely your CID module connector. No. 1 looks like the heater blower connector, but it shouldn't be harnessed there with those other connectors. No. 2 I've never encountered, maybe a rear windshield wiper connector?

I just wen through this same thing the number two is your voltage regulator plug.

number three is the ignition box

and number one plug on my 75 has a tach signal running through it i reired this to work with my 78 sc harness to the 75 car

do a 14 pin connector search and you will find my thread

but the 14 pin is as fallows for 78 CS

pin #

1 starter relay *yellow*
2 rear fuse panel *green*
3 oil temp sensor green/black
4 oil pressure sender green/red
5 backup light switch yellow/green
6 backup light switch grey/brown
7 rear fuse panel blue/yellow
8 shift lever harness brown/white
9 oil pressure switch green/white
10 cis warmup red/white
11 D+ *blue*
12 tach black/violet
13 heater blower relay yellow/black
14 B+ *red*

I got this info on this forum from another pelican member

hope this helps

Roger, many seem to prefer the stock Bosch CDI ignition units like this over the aftermarket solutions out there. It has the 6 pin male connector for the plug you show.

Do a search here - this has been discussed many times over.
