hey i have a hb that had the ls running in it will all si harnesses. my dumb friend spliced the harness all up when he did a ls vtec in another car. i bought a ls obd-0 harness will i be able to splice the two back together? like the injectors and other ramdon connectors he took off? or do i need to find a obd-0 si harness?

also when it is together i have a sleeved gsr block with type r pistons b16 head with p1 valves and all the trimmings how do i convert the obd-0 to obd-2 because i think the distributor, intake manifold, and throttle body were of a obd-2 head. not too sure though it might be obd-1

 

i forgot the ls has a obd1 alternator (green connector) that was already spliced and worked

 

if i were you i would just get another clean si harness. you can take the plugs off the teg harness and splice them into the stock harness but you cant plug in the teg harness to the car. obd0 and 0bd1 have the same alternator plug. and you really should convert the other motor to obd1 you need to buy a jumper harness for that.
