Fitting Instructions for all 13 Pin Kits and Relays

Take the 13-core cable into the boot through a 9/16" hole into which you have inserted the grommet provided. Find the vehicle wiring harness and connect the 7 core cable as indicated in Chart 'A', using the connectors and earth tags provided.

Refer to the appropriate instructions for the relay you are fitting and fit the relay and any external panel lamp (The TF2218/7 series bypass relays have built-in buzzers, so a panel warning lamp for the trailer indicators is an optional extra).

Test, preferably with the alternator charging.
