Hi guys, I have a VZ SS Ls1, i know this question has probably been asked before however i cant seem to find it anywhere but iv put a speco rpm gauge in my car, iv wired the pos and neg but cannot find the signal wire anywhere, the only sort of answer i could find is to wire it to the "purple" wire on the number 1 coil. or rip out the cluster and wire it in however i dont wish to pull it out. can anyone confirm this purple wire? or if there is a wire in the engine bay to link to. ( i know vx ss had the packs behind the firewall and it was a brown white? wire which was easy enough... but VZ SS dont have that)
Pin 30 (brown/red) on the cluster plug should be the signal wire for the cluster tacho. Disconnect to be sure.

Is it hard to get to? Do you have to take cluster out??
