Hi guys, I have just converted from obd0 to obd1 by making my own harness. Everything is great but I have one wire left from the obd1 ecu to hook up. It is the service check connector wire. Can anyone tell me where this goes? Thanks loads.

Dont hook it up to anything. When the cel comes on you can touch that wire to ground to pull the code.

ok great. So it wont stop the engine light from working or stop the car registering problems and giving me codes? if i really wanted to hook it up then i would join it to the existing service connector wire that isnt the ground?

you dont need to hook it up period. just leave it hangin like on all the OBD1's.
