anyways my harness is shot strait to hell and back so im going to need another one. the one that came on my b20 is cut in about 90 places, but i found an obd1 teg uncut harness local for like $40. that harness will work if i get the injectors and distributor.
here is what i have so far
obd1 p74 ecu
and im getting an obd1 ls harness.
FYI, OBD0, OBD1 and OBD2 LS distributors all share the same bolt pattern. You can use an OBD2 distributor with an OBD1 car, but the main problem is the lack of tachometer output on the distributor. The easiest way around this (that I know of) is to use an aftermarket ignition amp (MSD 6A, Crane, ... ...) that has a tachometer output. The easy thing without any doubt is to get a 92-95 LS distributor, but if that's not an option following the installation instructions for the spark box carefully will solve the issue too.
You can't use a B20's intake manifold due to its shape - you need an OBD1/OBD2 B18 manifold
i know i cant use the b20 im cause its like 10" tall so i gave it to a friend to make some ITBs out of haha. thats why i was asking if an obd2 im would work cause i will prolly just use his obd2 b18b im.
