Complete HD Wiring

This is an ADD on to our existing OBS fuel system kits at this time. This wiring feeds the pumps with 10ga wires instead of 14ga. If you have a Marty's Diesel E-Fuel system and you have an issue with the connector - this is an optional upgrade that you can buy that will eliminate the fuel pump plug. We include the fuel pump plug for convenience, it is NOT required. If you are wishing to go 3x's larger on the wire size than required for the fuel pump - this is the kit for you. This kit will come with a red wire with a female spade already crimped on that you have to attach to position #87 on your relay. You will then have to route it to your fuel pump. You will then trim the wire and install a ring terminal that you will attach to your positive stud on your fuel pump. You must let us know which fuel pump you have so we can send you the right size terminals. The black wire will come with a ring terminal already installed on it that you will install on your fuel pump. Then you will route the other end to the closest GOOD ground and trim the wire to length. Then install the correct size ring terminal (supplied) that matches the bolt size you are using. If you are making a new ground, always OPT to drill AND TAP the hole you are creating for the ground. Then make sure you protect that ground
