im using obd1 stock z6 injectors. i ended up wiring all the injectors to the ecu, wiring all the yellow/black wires to a wire that gets 12v power. idk if it works or not cause i cant get the car started.
i have to figure out were all the hoses an plugs go.

ok. there are 2 blk/yel wires that come from ur 2 injectors that are on the dx.std harness. solder those 2 together and from that, add a 3rd wire and run that 3rd wire to the yel/blk wires that come off the inj. plugs and solder them all together. ill draw u up a diagram to explain better

Double check the distributor wiring. If somethings not right there it won't fire at all
