Turbo Timer install ques

[sighpost]

Getting into my turbo timer install and need a bit of help with the parking brake wire feature. Has anyone isntalled one of these? Where is the best way to locate the parking break wire? And how do i locate the "On" and "ACC" wires in the wiring cluster ?

between the 2 red wire in the cluster, i just guessed which one. your not cutting them, just tapping them. if you guess wrong, just switch wires. its one of the 2 thick red wires that is in the same cluster as the really thick black wire. as far as teh parking brake, no clue, didnt do it, too lazy.
