flyin brian Posted January 18 Posted January 18 Does anyone know or have a wiring schematic of the horn circuit from the the steering collum out. Or what color wire Im looking for coming out of the steering collum. I read somwhere that the horn relay is under the dash but I thing mine is on the core support. Quote
Rob Peters Posted January 18 Posted January 18 Brian, We have some wiring diagrams in the Electrical Forum: https://www.firstgenmc.com/forums/index.php?/forum/18-electrical-tech/ 1 Quote
jft69z Posted January 18 Posted January 18 It's a pretty simple circuit Brian. Basically grounding it at the horn button completes the circuit for the horn relay, to power them up. 1970 is different than later years in relay location (1970 Core support, later years on firewall near brake booster) and wire color (1970 is Black wire, later years are Dark Green), but the pics blow are for a 70, which you have listed in your profile. If it's different now, let me know. 2 Quote
