They are all powered by the chassis. Should be the common wire between them. DONT ground them. The ecu sends a ground pulse to open them. I think youve got it backwards man.

No, I ran a new wire for the injector driver, that ground is what i ment. I ran i new wire for one and four. I found it to be powered by the orange and black wire at the B1 plug under the dash pin 17 for 1989 ma70's

I read in a different thread some where that it's safest way to power your injectors from a switched power coming from your ecu.
