W3LSH’s how to on uprated headlight loom
I thought it was about time I uprated the headlight loom on my mk2 golf again after changing my original cars loom from pre 90spec to 90spec with the g60 conversion.
I’ve take some pics along the way to make a ‘simple how to’ for anyone who may want to do the same
The difference is incredible too
Parts needed
1. A Relay with 30-amp switching capacity

2. 20-amp fuse
3. Quality fuse holder

4. Blade connectors, blue & yellow type
5. Ring connectors to connect to the battery
6. Suitable cable
Total cost? Under a tenner (uk money)
To start with you need to find the wire that provides the input voltage to the lights

I then cut this wire to have the required input and output for the relay

spade connecters were then added

I quickly measured out the cable I would need to go from the battery (+ve and –ve) along a hidden route on top of my intercooler so the loom would not be visible
The two battery ring connecters, fuse holder, and relays were added

After the wiring was put in place, all I had to do was connect the two connectors I had cut earlier to the relay

Here’s a simple pin diagram of this

By running the wires across the top of the intercooler (or rad) the loom is also not on display - but gives a different result to standard

Hope some people find this useful
