I currently have a obd2b y7 powered hatch and want to add in an obd1 z6. I went out and bout a 99-00 harness but now I discovered some of the wires close to the ecu were cut and soldered back. These are the exact wires that were cut and re soldered..

ecu plug C

pin 10 vtm/vtec pressure switch
pin 17 map
pin 27 tps


ecu plug B

pin 1 igp1 (power)
pin 2 ground
pin 12 vts/ vtec solenoid switch
pin 13 igm ignition control module (rpm)
pin 20 lg2 logic ground 2 (ground)


Should I get rid of this harness and just modify the y7 harness? Or should i not even worry about it. My wiring guy recomends to just get rid of it since the solder can possibly fubar some signals or mess with the ecu power

 

Anyone? I'm inclined to do what he says but it's always good to hear otheres thoughts.

 

absolutely keep the stock harness trim the loom back and peel the wires for all the sensors map,tps, iac ect and add vtec really not that hard to do


check ff tech net for info on the 3 wire iac conversion and wiring the vtec
