2007 dodge ram
I have two 100 watt driving lights I want to install behind the grill and have come on with the high beams
picked up a relay and was planning on wiring it as follows:
30: 12 guage to battery positive with 20 AMP fuse
87: 12 guage to 100 watt lights
86: to white/green high beam wire
big question I got is should i be using a diode on my high beam wire to prevent voltage back feed??
not sure on these new fancy 'computer controlled' systems lol
and is my pinout correct? i see some people reverse 85 and 86 not sure if they are interchangable and that is why??
