Hello all!
Am installing a PMD relocation kit to inside of front bumper, can i ground the heat sink to the body or do i have to ground to the IP? New to this site, Lots of great info! Thanks for your time.

 

I would think u could ground it to ur front bumper cuz its to ground the pmd and the wires to the pmd...so id say yes u could

 

The extension harness i have is just a plug and play, no wires to ground? The heat shrink has a threaded screw hole. Is that sufficient to ground or do i have to splice into the harness?

 

U shouldnt have to grond the heat sink the harness is grounded to the IP and u plug in the extension to the connecter and the apmd is grounded...u dont need to ground the heat sink..

there should be 4 drilled holes to mount the pmd to heat sink and there should be another hole drilled to mount it...

no need to ground heat sink

 

I noticed when the previous owner relocated the pmd ( to a heat sink above thr exh manifold) he spliced into harness and grounded to engine. If i dont have to do that all the better! Thanks for the info! P.S. I do plan on pulling his harness and goin with the new one right from the IP.

 

The IP harness ground needs to be grounded to the IP and/or the drivers side battery ONLY.

The PMD heatsink does not require any ground at all but there is no harm in adding 1 and some manufactures even recommend it.

Pictures 2 and 4 of this link show the proper location of the IP harness ground(black wire):

That makes a little more sense. Much appreciated.
