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?

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. Cheers, Ingo
