1995(earlier too)-1999 High and low on at same time.
Has anyone out there ever figured out how to do this mod? I was thinking of buying a new set of headlight harnesses and adding a relay for low and high and then use a diode between them. The older trucks don't come from the factory with headlight relays so it makes everything difficult. I would leave the stock wires in place just incase the mod didn't work so that way it would be a really quick change back to stock.
Any ideas any one?

I found this. I don't know if it will work for your year truck
Or this is $28 and says it will work on your truck.

go on LMC truck's website I have seen a kit in their catalog before. not sure how much it costs

They DO have kits at LMC, but they are just relays like I already have laying around. @Pikey what was done in that video won't work with 95 and up trucks because the headlight switch and bright switch are part of two separate systems in terms of connectors. The only place they meet it the headlight switch, but the lights would burn up the light power feed.
If I only buy two sets of headlight wire harnesses it will cost me like $20 for the mod since I have the wire, relays and diode.

There's some material for you (supplied as a response to a tag I made, there) in the Guess the Next Poster thread. It might or might not help. It's for 99-02 trucks ... which have the same kinda issue you do (no relays).

I'm not sure if the 95-99/98 OBS trucks are set up like that.
The pinout for the headlight switch is this:
Pin Wire Color Description B Gray Courtesy Lamp C Red Battery Fused Feed D Pink Ignition Fused Feed E Dark Green Instrument Panel Lamps Dimmer Switch G Yellow Headlamp Switch Output H Orange Battery Fused Feed L Purple Interior Lamp Defeat Switch M White Courtesy Lamp N Purple w/ White Stripe LED Dimming Signal R Black Ground S Brown Park Lamp Feed
The switch between the high and low is based in the wiper control lever. I was simply going to tap into the low and high factory wires and use those to control the relays, then using new headlight harnesses I would attach in the headlights switched via the relays. I could then just add a diode which I have laying around into the circuit. With having the aux fuse box I have the open terminals and if the system failed I could still use the factory headlight harnesses.

I have a GM electrical manual for a 1995 truck. If it is the same and you need a diagram, I can take some pics of it for you and post them.
