To start I have an 85 k5 blazer changing to TBI with all stuff from the same 1988 truck. I have a 7747 with a AKAH chip.
So first question what is the easiest way to connect the harness to the 85 truck harness, Do you just splice together all the common color wires in the 85 bulkhead connector feed anything new through a new hole in the firewall?
@nd how do I get a different chip done? AKAH has t400 kickdown and I need to convert it to something with 700r4 lockup. They both use the same wire to control the transmission function just need chip to control it.
