cross gen wiring

[dohcfiend]

just out of morbid curiousity. the 3.4 tdc fiero swap is popular for sure it is also one i want to do one day.

could u make the fiero harness work on a 3.4? could you remove that plug and drop a 2.8 distributor in it? and would the newer style iac and tps sensors communicate with the older fiero ecm? of course id have to get a new eprom i am sure.

the di system is great and all but it is too much stuff to troubleshoot when it doesn't work, with this system i would be looking at a coil, a distributor and 3 sensors at the top of then engine.

RE: cross gen wiring

Does the TDC even allow for a distributor because of clearance?
If it does..then just plug it in. Personaly..I think the DIS is far superior to the old rotor/cap...even in reliability. The TPS is good..the IAC im not sure of.
