conversion wiring issues-please help
hope some engineering type here can help me with this one.
i'm converting my 84 cease fire to tpi. have an 85 harness and can resolve most compatibility issues except for the following:
in the under dash area there are both a 15 pin and 8 pin connector.
on the 8 pin connector, pin E the 84 circuit is titled "vehicle elapsed time" (circuit # 421)while on the 85 harness the same pin is "fan request" (circuit # 992). is there a need to maintain this circuit or can i just cut the wire and insulate it?
also on the 8 pin, pin F of the 84 harness is labeled "Air conditioning clutch"(circuit # 59) and the coresponding location on the 85 harness indicates blank or no pin/circuit according to the gm shop manual. is this where the ecu finds out if the a/c is on to bump up the idle speed? since the shop manual does not identify any other lead as a/c clutch sensing can this pin be left in place or must it be cut and insulated?
on the 15 pin connector, pin B the 84 circuit is identified as "tps & coolant temp sensor" (circuit # 452) and the corresponding 85 pin is identified as "coolant fan" (circuit # 935) how should this crossover be dealt with?
