Hi everybody
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
85: Ground
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??

thanks dan
