I have an 82 z28. I pulled the 305 crossfire out and put a 350 with a carb in it and I removed the ECM. I put in another fuse block to wire in numerous relays and such that need ignition switched. My issue is I need a good ignition wire to tap into. Any suggestions?
Thanks

 

You don't want to be using the coil ( pink ) wire to power up relays ( reduces power to coil )
so I would be looking at any of the other feeds direct off the Ign switch like the one that used to power up the now redundant ECM.
What did you do with that wire?

 

My pink wire goes directly to my msd box. I haven't done anything with the ECM wiring under the dash. I just unplugged the ECM and pulled it out. I pulled the wiring from under the hood but under the dash I figured why bother. Would that be using a fuse? Do you have a wiring schematic?

what relays do you need power for that you cant just run to a stud from the battery?

 

I got it taken care of. I used the ignition wire that was for the tbi's. since I no longer have fuel injection that worked. thanks
