Battery cable through firewall options

[DT69Cam]

Are you guys using a bulkhead connector at the firewall to run the positive battery cable through or just a grommet ?? I'm not sure I like the idea of a LIVE cable connection at firewall using a bulkhead connector. I was also considering just a grommet and run the pos cable to the starter. I hope those caps on the bulkhead connector will prevent accidental contact.

Go to someplace like Aircraft Soruce and get cable end covers. They are like a flexible short spark plug boot to cover exposed wire terminals.

Here you go- a neat solution-cost maybe $5 at your local pull-a-part

Not only to hook up your starter but also a terminal block for a couple other connections-

Yes, I'd reconsider on the bulkhead. They are damn useful for lots of things.

I have used these many times with great success

I used the same bulkheads as dse.

Thanks everyone.

I have been running this bulkhead connector from AllStar and have been very satisfied.

I'd also consider not leaving the main battery cable live. Use a Ford solenoid or equivalent so it's live only during cranking.

x2 on both of these. I have the All Star Performance bulkhead and a Ford solenoid, both work great.

I've used the heavy duty rubber grommets successfully. I can't remember the brand but I'll attach some links. I've used them through frames and firewalls with no problems and they've stood up well. I'll look for a brand and part number tomorrow.

This is exactly what I will be using. Damn thing is huge though. Hope the engine is not too far back with the holley mounts and LS3.

The battery grommet is another option. However, I'm using 1/0 Batt cable. Actually, I think the 1/0 gauge cable is 5/8's. I will have to double check. Thx.

I'm using this with no problems so far. I may switch to the bulk head since I'm redoing a few things. I currently pull power at the starter for the Speartech harness. It would clean things up just a bit if it was on the firewall.

Not sure why guys don't like the bulkhead. Even DSE uses them and supplies them with their battery relocation kit. Put a protective cap on it and you are good to go.

Also curious if DSE uses a relay for the starter cable. I am pretty sure GM does not use one for the trunk mounted batteries in the 5th gen Camaros.

I have contemplated using a relay on the main 12v cable but instead I installed a 250amp circuit breaker back in the trunk next to the battery so that it will trip if the cable shorts. I also have a master disconnect switch mounted in the trunk so I can kill power when the car is being stored.

[cpd004]

I too, am running a breaker in the trunk. No solenoid. My G8 has a constant live feed from the trunk as well. The only reason I didn't initially go with the bulk head is that I didn't have one on hand but did have the pass through linked above.

I picked up one of these at a local electrical supply store. It eliminated two connections at the fire wall that you would have with a bulkhead connector. It is water tight and holds the cable securely.
Working well so far.

I didn't see it mentioned but I used the Ron Francis bulk head fitting. Didn't want to put that big of a hole in the firewall after all the time spent filling holes, but everything I looked at needed a big ass hole.

Have a part number?

[Chuff]

Does any have some more information on the BMW part in the previous post?

After a couple of days of Googling I've had absolutely no luck identifying this BMW part.

Year. Model. Part number. Anything more than just a photo might help.

Anyone?

Thanks.

Chuff.

Here's the E46 firewall pass through. That should get you started.
