HId headlights

[87gtVIC]

I just found this great diagram on doing the relay upgrade even though he labled the relay pins incorrect lol here is the correct layout:

85 ground
86 multi switch input
30 starter solenoid
87 headlights

It was for a 4 eyed fox body but it should be very similar i have not checked with my EVTM yet to see if they are in fact the same



This is using a 4 pin relay..i am just gonna use 5 pin relays because i have a whole stash of them

I also see some guys running circuit breakers between the battery/ solenoid and the relay. Is that required?

those..are..UGLY! I'll start working on the wiring, get everything laid out and set a game plan. Then Ill go form there

That diagram doesn't show any fuses!!!!!

[87gtVIC]

oh so i guess you would want a circuit breaker then?

Using 5-pin relays also makes it easy to wire your fog lights so they go off with the high beams. The 'extra' output on a 5-pin relay is 'hot' when the relay is not triggered, and is switched off when the relay IS triggered (sends the juice over to the switched output). If you use this 5th pin-output from the high beam relay to provide power to the power input for the fog light relay, it will kill the fog lights when you hit the high beams. Also you can still turn the fogs on and off as you wish(when the high beams are off), because you can still have the fog light relay trigger wired to a switch.
Most folks don't care, but this is how fog lights are 'supposed' to be wired in a 4-headlight system, as 'required' by motor vehicle laws in some states.

Found another nifty diagram....with a 5 pin relay this one uses a fuse :p

whoa..massive wealth of knowledge in nothin flat. i love this forum :P

I fixed the other diagram i found to the correct information:

Real men don't use fuses, Pete.




Lol.

Some people used 30 amp circuit breakers. Is that sufficient? And can I substitute the 30 amp breaker for a fuse?

Either one should be fine.

great!

For the record the fancy black diagram i have pictured on the previous page has to correct color wiring. red/black for the low beam and light green/black for the high beams.

Hi 87gtVIC

Why are you using two relays when you only need one?

Pin 86 - From MFS low beam output
Pin 85 - Gournd
Pin 30 - 25 amp fused supply from battery
Pin 87 - To low beams
Pin 87a - To High beams

I am using two relays because your way does not make sense to me.
