Just a couple of quick wiring questions - I will probably have more later on, but just want to get a couple of thoughts worked out. Sorry if these are stupid, but I am not the smartest guy in the room when it comes to wiring. Very overwhelmed, but I am just trying to break it down 1 piece at a time.

Setup - MK4 complete kit, with a Powerjection III (PJ3), MSD 8352 Ready-to-Run Distributor, plain coil and in tank fuel pump.

1 - I am running the PJ3 Orange Wire directly to the RF fuel pump wire. That being said, I am not really thrilled about having an Inertia Switch and wanted to know if I can just cut the Inertia switch off and solder the wires together. I am sure this is not recommended by FFR but I am just not interested in having to hook up this circuit.

2 - Orange RF Coil Wire. Please confirm that I just connect this to the + side of the coil.

3 - I have read that each circuit requires its own ground. Is this truly the case? If so, I will need to take every ground wire that is in the RF harness and terminate it to its own chassis ground? I just want to make sure that all my lights, fan, fuel pump, gauges, etc work and if a separate ground is required, then so be it.

Thanks in advance.

Hi PhoneGUy,

Hope you're enjoying your build so far. Here are a couple comments to your questions:

1.) An inertia switch is a smart system to have, but you can change anything you want on the car. You should be able to remove the switch just by connecting the proper wires together, so that sounds right.

2.) Yes, with a plain coil, the Orange Coil Wire would just connect to the + side of the coil.

3.) The RF harness has grounds worked into it, so you shouldn't have to do anything differently from the schematic. It won't hurt to have some extra grounding, so no problem with a little redundancy there.

Let me know if you need anything else!

Jason - Thanks so much for the prompt response. I almost called you but I thought better of it as someone else might have a similar question in the near future.

I am trying to get everything completed so that I can get my engine started by Christmas - No more distractions aloud!

Cheers!
