3800 wiring.............

[FieroBUZZ]

Well, I for one can't understand why people don't enjoy mating their 3800 and Fiero wiring harnesses.

I think you still have a few extra wires that you do not need. If I can be of any assistance feel free to ask and I will give it my best to help figure it out.

Gary, you must be into masochism almost as much as me. Even with that spaghetti I am sure you and the 3800 guys will be driving and smiling while I am still puzzling and motionless...... HEY! I can take Steve's title from him!!!

I'll be more than happy to pass on the time honoured title

EEEEEEK!! Gary! Just use the 3800sc harness and route the wires to the back of the engine. (might have to extend a few..) and hook it up to the 3800sc ecu. Then splice in the tach to the ignition module white wire, the temp gauge to the temp gauge on the 3800sc (green / white I think), the oil pressure gauge spliced into the 3800sc feed, speedometer stays the same.. ummm... What am I missing here guys?

oh, and get some power to the ecu and power to the ignition module. (ignition module should be switched.. )

We need to talk and figure this out together garry, I have a cleaned up 3800sc harness if you want to have a look at her
 

Cheers!

just out of curiousity, this sounds like you are eliminating the fiero ECM and replacing it with the 3800?  would that be right or do you piggy back it?
Just wondering. I had the impression that most swaps do a piggy back but that could be wrong too.

nah, there is absolutely no need for the Fiero ECU.
