hi i am getting ready to run my power cable to the battery and was wondering if you guys know of any plugs up front i can run my cable through to save me time thanks 91Z is the car

 

I couldnt find any. It's easy on my 4th gen, just use the ecm grommet. On my thirdgen however, I had to drill.

 

best bet is to run it thru the firewall

 

There might be one on the driver's side of the firewall, in the brake booster area; it's about 3/4 inch diameter. Some cars have it, some don't- but if you do have it, knock it into the engine bay with a hammer and punch; crawl underneath the dash to knock it out.

As long as you make a ton of measurements against existing things in the firewall, it's not that hard to drill a hole. Just make darn sure you know what's in the way! Again, crawl under the dash to drill the hole, drill into the engine bay. But look around on the firewall first to find out what you can drill thru- and run that wire thru a grommet!!

 

Wow I guess I got luck on my car I have that hole that is about 3/4 running thru right by the booster. I have run everything thru it. I found it when I traced the wire for my car alarms siren. I managed to get my 4 gauge wire thru with no problem. Got a few 10s thru there as well. So if you ahve it there is plenty of space for a steroe power wire!

 

look in the MSD catalogue and theres a thing so you can mount the coil in the car.. a firewall pass thru.... if you mount a spark plug end to ur cable you could use that

 

NO! That bulk head is for high voltage, NOT high current. There is one for high current in the Summit book though, it's for passing the battery cable though a mettle plate.
DO NOT use the one for a remote coil.....

 

or how about just find a nice piece of flat metal on the firewall (it exists just below the heaterbox on the passenger side footwell), using a sharp drillbit drill an appropriate sized hole and protect it with a gromment. then use black silicone and fill the rest of the open area in to keep water out, and ur done.

why all the expense, complexity and danger of things from summit??? you won't find professional car audio shops doing anything but drilling....a factory grommet is fine if you can find one...I know my 3rd gen didn't have it.

doh thats why we have these discussions... i woulda never thought of that... although i prolly shoulda alreday known that.

 

where is this grommet i hear so much about becuz the only thing i got is the pass thru to the hood cable. any pics

 

vehicles of different years and models even will have grommets and such in different places. I know my 82 Zee has a hard plug in what appears to be a 1" hole, prolly for a clutch cable that I didn't have (auto). others will be different.

double check both sides, make sure its a good/safe spot, and drill yourself a hole. by far the easiest and cleanest way to do it.

Hold on, re-reading my post, no I don't see where I said to use the bulkhead, just letting Bob and everyone know there was a difference and that both where out there if ever needed. Maybe I'm missing it, I'll re-read it (my post) some more.

I had to get a set of these after a dead PPI amp cooked the terminals off my 80A supply.
