I am currently in the middle of a 2013 LS truck swap into a '86 C10. I am trying to connect the TCC wires between the 2 trucks. I have the 2 (lt blue/wht stripe) wires ID... both come from the same pin at the '13 ECM. I have ID the lt. blue wire & brown/wht stripe wire from the '86 switch (in cab). The '86 lt blue wire comes thru the firewall with a green wire both end at a connector, the green wire then runs single to a connector (byself). looking for help with how/what to connect at what point(s)? any assistance would be greatly appreciated .... thank you again!
