Did it come with GMR pick up?
yes, i hooked it up to the green wire going to the coil.
Looks to me the only possible choice is to trigger via injector wire. See on a couple of sites, suggested for '96 up.
Worth a try to see if it'll trigger from there.
Is that the power or trigger wire?
According to instructions (no comment as to what I think of the author), it appears to read off pos, now thats freakin strange.
i am confused too Rick. Imhave red ro a 12v switched, ground to ground and the gmr to the green and yellow wire at the coil. I could try the injector tomorrow.
i have been searching but coming up empty on the net, most have msd box.
Are you hooked to the coil power wire or trigger wire?
honestly i tried both of,them - red wire and the green/white. Everything else works but no signal.
From what I see on the web, green is suppose to be ground / trigger side, other one is power.
Try running off injector wire. Odd part, shows it hooking to pos on injector as well.
Frustrating that they can't even include decent instructions, lots of conventional style coil vehicles still out there.
