Im new to the forum so hello,
I have a 91' z28 and was wondering if anybody has ever had sucess with making high and low beams stay on with the fog lights, the lighting on these cars is poor and also i think i would look nice to have them all on. Ive been looking at some diagrams and looks like i can bridge the relays but wanted to see if yall have suggestions. Thanks

 

It's a common upgrade among the truck crowd-I build 4-HI relay upgrades for those guys who like to have all headlights on at the same time and you can have the fogs on too-but, keep in mind DOT rules states a vehicle can have no more than 4 forward facing headlights on at the same time-so you may get stopped. For the truck guys I incorporate a plug-in pigtail for that feature where unplugged the lights are normal then with it plugged in or "jumpered" you have the 4-HI feature.

So yes, you can do it and yes the light output is amazing that way but be aware of Johnny Law! Lol

 

You make these kits to sell?

 

Currently I have kits for gbodies, trucks and 2nd gen fbodies but I have everything on hand to build them for a 3rd gen if you're interested. For headlight relay kits I have the following:

OEM replacement harnesses

OEM replacement harnesses w/relay upgrade (4-HI optional)

And I offer the above harnesses with delay off feature as well. These harnesses Ade for headlights/aux. lighting only but I can so supply an entire front lighting harness with any of the aforementioned features. PM me if you need more details!
