I shall be making up looms to sell in the next week. once I've found out how much the plugs are for the lights I can make the whole loom plug and play. even a muppet can't connect this wrong.
Once i've found out the cost of the these plugs I'm hoping the cost will be about ?15-20 for the looms to you.
The looms will be made up so installing them is as simple as pluging the loom onto your lights, the old loom to the relays and the relays to the battery + and -. this will all be done without cutting your existing loom or having to solder anything.
