I have a 92 z28 that i put a ls1 t56 from 01 z28. I have a harness built by pocket. The problem is when i go to plug in the battery it makes the starter start clicking. I am using battery cables from the 01 z28. The positive cable goes to the big bolt on starter and the other positive cable goes to the alternator and the third positive goes to the power distribution block. My negitive cable goes to ground on fender and ground on block above starter. I have a ground from driver head to firewall and ground from block to k member. Any help would be apperciated!

 

Seems like the starter command wire(typically purple and 12-14 gauge), is connected to hot at all times battery power or a relay is stuck on. Not sure about your set up, but starter command wire is getting power at all times and not just when ignition is on crank

 

Yea i found that my power wire to the starter was touching the solenoid wire so it was making it have power all the time

 

Wish I could say I've never done that.

At least it is an easy fix.
