3 wire hook up

[69BUCKET]

Curious as to where you guys are splicing into to connect wires from ls harness into truck harness....anyone care to give up some knowledge of best place and which wires they spliced into?

what you need is switch on power....constant power...and grounds...
for switch on power I used the big switch on hot wire going to my hei...for constant hot I wired into the junction terminal on the firewall...grounds are self explaining ..but you do need to have ground to engine to body to frame....

my truck didn't have an engine in it...so i guess i am asking more specifically which wire is the switch on power wire at the fire wall? Constant i have...and 3rd wire is for fuel pump which is hooked up....have new ground straps as well.

if the original trucks wiring is still there the should be a wire coming thru the firewall that went to the distributor. ..looks like a 10g wire...i cant remember the color but i think its red or pink....that should be a switch on wire...you can verify it with a volt meter...
