Wiring a Towbar 12 N socket with 7 way Bypass Relay

This job requires work on the vehicles electrics and might void your warranty And if done incorrectly could start a Fire

thats the disclamer out of the way

Gone are the Days when you'd just scotch hook the trailing end of the 7 way cable to the loom with the bulb failure system and Fiats notoriously small cables it cant be done for fear of melting the loom and having the check Bulb light come on every time you use the socket....

you dont need a towbar to always need road lights if you use a strap on cycle rack for example that blocks vision of your road lights you will need a light board for example..

I have left out the towbar bracket fitting instructions as these are specific to the brand of towbar you have bought

The stuff you will need are
12N socket and mounting hardware
2 mtrs of 7 core wire
1.5 to 2 mtrs of 2 core twin 1.5mm is fine
a Reel of Single core 20Amp rated cable
7 scotch hooks
7 Way Bypass relay
a blue eyelet crimp
Fuse holder and associated spade crimps
Soldering iron,
Screwdriver,
wire cutters,
stanly knife
wire strippers
insulating tape
Cable ties..
A working lighting board is handy to test
I think thats it......
