ok, i hit a wall... literally (I didn't Crash)
 

I need to route a 4 prong molex plug through my firewall with four 20ga wires attached. I would like to get away with the stock holes and gromets, but if I really need to, where do I drill a new hole and install a gromet? my interior is already installed and I forgot to put this plug through first.

please help if you know where to wire something like this through.

thank you in advance for all your help,

Molex like the computer PSU connectors? Just use a small screwdriver to remove the pins from connector and push them back in on the other side.

i actually have a tool to du that. it's a little thin wall tube and I have already done that and electrical taped them as a bundle. this whole thing is for a home fabricated CO2 intercooler sprayer, actuated by boost pressure or intake air temp.

thank you though,

I just cant seem to find a way to follow the main wire harness through the firewall on the passenger side. i puuled the charcoal can and the coolant overflow, but to no avail. how can i add my bundle to this harness?

thank you again,

there is a little nub on the grommet that you could cut and thenuse to send it through, it looks like this is the sort of thing it was made for.
