Has anyone used a relay to run the power tailgate motor?
Where did you put the relay? Did you have to run any new wire from the front of the car? Any help and pics would be appreciated.
Thanks Brian

What is your purpose?you want to avoid the high current through the switch?

you will have to use two relays...one for up and one for down.

You will still have to run a 10 or 12 gauge wire from the battery or starter solenoid.

you can use your original wires from the switch to run the relays,or replace them with smaller ones.but then you will have to run another set of large gauge wires to power the motor.

Yes I would like to reduce power through the switches
there are three switches in my harness I'm not sure where I would cut the relays in to have all three work

Only thought I would need one but two makes sense

Am planning on adding 10 ga power wire front to back do I also need to run a ground wire

am going to use original wires to run the relays

That is fine.

But now you will have to run another 10-12 gauge to the rear.to supply the power to the motor.This will mean three large gauge wires will be run.

your existing wires can be used to control the relays.two relays........one for up and one for down.both can tap off the power wire to supply power to the motor.
