I'm installing a TPI setup in a 1987 chevy truck(originally TBI), the setup i'm using has a 87-88 intake w/cold start, but the harness and ECM (1227730) is 90-92 speed density. My question is how do i wire up the distributor (TBI distributor), can i wire up the module to the 90-92 harness and what pins go where? My harness is an older Painless kit that all the tags have fallen off (wires not labeled), so i have had to go through pin charts to narrow down some of the wires. If anyone can tell me what pins on the ecm plug go to what pins on the distributor that would be greatly appriciated. So far my references have been through chevythunder.com and have been great so far but not sure about if i can use the TBI distributor and module or do i need a different dist. or module?
