Good kit, plenty of length for cable run. Would be better if ALL wires were shielded, not just some.The wire diagram IN the box is a bit confusing and doesn’t explain the switch setup; you have to look at the wiring diagram ON the box (lucky I didn’t chuck it out like I normally do!)Supplied switch doesn’t fit new hilux, so have to source one from elsewhere.For the price, it’s a life saver having the relay, switch, piggy back all setup.

What a nightmare. One blown fuse due to the switch wiring diagram being the wrong way round. Not to mention having to buy a piggy back adapter for a Holden Colorado with a 2 pin connector that did not fit this harness. Cut and replaced both 2 pin connectors.But XDS-400 22” is a great light bar. Buy the bar go elsewhere for the harness if you have a Colorado.

A week ago I purchased a couple of those Korr XDW Series 45W Driving Light for my old 2001 Hilux ute 2WD along with this Dual Wiring Harness to power them up with. First laying the harness out inside engine bay, then connecting/fixing everything in place. Too Easy Lemon Squeeze. I must be honest, when I first tried to spark them up, nothing happened. HMMMMMMM. Trouble shooting, after wiggling all connections, thought, Hay Look they've supplied two Relays, may be I'll try the other one. Yer right; I had connected the 24V one so simply installing the correct 12V Relay which worked a treat. Very Happy with this Dual Wiring Harness, simple easy plug and play, just watch out for those pesky 24V Relays.
Wiring made easy work and simple to follow instructions
