Resolved ECMlink 98 ECU to 95 ECU

[joejoe13]

I recently purchased a 95 ECU with ECMlink V3. I have the original ECU (98) still in the car. When I switch the ECUs someone had mentioned switching wires but were very unclear which ones need switching. I know that if you do not switch the wires the car will not start. Any help would be greatly appreciated. Thanks

You need to switch plug wires 1 with 2 and 3 with 4. Then with dsmlink, you need to invert you CAS signal. Then you should be ready to go and tune.

I need to disconnect the battery first right

Absolutely! Always better safe than sorry!
