Getting wires into the ECU box?

[NoQuarter]

How do you get wires into/through the ECU box?

I have some that just pass through as it is a great entry point through the firewall into the under-dash area. I also have some that stay in the box for things like the flex-fuel module.

Currently, I just pass them over the top, and allow them to squish down a bit when I screw the top back on but I am looking for something better. I could cut the existing rubber grommets but have avoided that so far.

Been looking at various grommets, firewall pass through style, water-proof bulkhead type fittings, etc.

What do you think?

These questions exactly are what spawned my other thread about moving the DME/JB4. My original idea was if I made an aluminum DME Box, I would use the round milspec connections to bring wires in and out, etc.

I just poke them through the existing grommet iirc but the best way would be to drill and install your own grommets as needed:

Quick, easy, and VERY effective. Just use the right size/type.

Do you have a link for an assortment like that? Amazon and Ebay just turns up the simple ring/washer style

FWIW I always have always used the circular style ones:

I didn't notice the circular style ones where you make you own hole to fit. Thanks!

I'm currently working on this, I bought this: https://www.amazon.com/gp/product/B002X4AFL0/

And I'll cut a hole in the grommet plug and run my wire through. I may just cut the radius and slip the wire through that way, good when your wires have big plugs.
