Craig76z Posted June 29, 2016 Share Posted June 29, 2016 I'm going through the process of rewiring my 78 2+2 with the ez wiring 21 circuit kit. Two questions, which circuits need relays and which circuits would you add relays? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 29, 2016 Share Posted June 29, 2016 This should answer the first part - http://www.atlanticz.ca/zclub/techtips/wiringdiagrams/78_280Z_wiring.pdf Many people add relays to the headlight and the running light circuits, to take the load off of the switch on the top of the steering column.

heyitsrama Posted July 13, 2016 Share Posted July 13, 2016 Im with z mouse on that one, im in the processes of rewiring my 260 right now with a modified stock harness, adding in a total of 12 relays. { 2 head lights, 2 front blinkers, 1 wiper motor, 1 washer pump, 1 tail light, 1 AC, 1 reverse lights, 2 rear blinkers, 1 radio) maybe i don't have enough........ but on my 240 the indicator switch started melting, so id rather not live though that again.

bramagedained Posted July 13, 2016 Share Posted July 13, 2016 I have relays for the electric fan, starter, high/low beams and running lights. Quote Link to comment Share on other sites More sharing options...
