Wire colors and function

Now if you haven't cut the connectors off your dash harness, you can de-pin the wires you need, and pin them into new connectors. Then you can put female connectors on your gauges to make it where you can plug and unplug the gauges from the harness.

Here's a source for the YPC connectors. You have to buy the pins separately.https://www.hi-1000ec.com/product/1135

If you want to go down that path, I can advise you.

I attached the latest update to my LED light list. Note that sometimes bulbs disappear from Amazon. I usually find out when I hear from someone trying to buy from the list. Here is a suggested source for the H4 housings:  *Link removed by SteveJ* Cheaper option: https://tinyurl.com/mr66wfd2

I don't use the relay wiring kit that comes with it, but you could repurpose one of the relays for your high beam.

I bought some 6.3mm connectors for this job last year so connector wise I'm ready to go. I do plan on depinning all the pins/wires I don't use and pulling them out of the harness.

As for the LED head lights, I've been running H4 headlights since I bought the car in 2009. I will add headlight relays since I already have the harness out of the car.

For the backlight on the gauge (single white wire). Does this also have to go through a relay with the wht/grn + red/blue wire or can I just by pass the dimmer?

You may need to rewire the return path for the lights on the heater control panel and hazard switch. I'm not sure off the top of my head.

Based on the diagram I'm looking at this is what I see: (this diagram)

Red/Blue goes from the dimmer to the hazard switch.
Green/White goes to the combination switch.

Using your previous example I figured another relay would look like this.
Green/White -> 86 & 87
Red/Blue -> 85
Dash lights -> 30.

I'm 100% sure on that but it makes sense to me. Would you agree? I figured the lights were driven off power and ground but clearly I was wrong.

You're overthinking it. Why do you think you need another relay. The gauges are grounded, so they have a return path. The green/white wire goes to the white wire on the gauge. The circuit is grounded through the ground wire on the gauge.
