For those who have corroded or damaged 1/4" terminals, or want to keep your wiring factory looking, you can go here

The 1/4" female terminals fit inside the factory housings without modifiction. The 1/4" males only require the removal of a tab on the spade itself. As for the housings, I'm not 100% sure, though they appear to be identical.

This is important: You need a proper crimping tool, NOT a $6.99 cheapie from Radioshack or your hardware store, to properly crimp these connectors.

since they explain it best. Plus, they offer tools and supplies for good prices. I've used their heatshink connectors, tools, and wire, and they're of good quality. Look around the site and see what they've got.

I recommend the Eclipse crimp tool frame, which is cheap and accepts interchangable crimp die sets, as well as accepts MSD crimiping die sets. As for the die set, you want MSD-3506 (for amp terminals) or the 3509 dies (for their weather tight connectors) available from Summit Racing. Be warned, the 3509 is not correct for this type of terminal (I got it because I also had the weathertight connectors). It will get the job done, but it won't be perfect.

Terminal Town also sells a crimping tool that crimps 8-4 gauge terminals for $27. After using it, I don't know how I got away with using large pliers for car stereo installs (yes, I'm ashamed).

 

Ditto's to everything you said.

Damn, I didn't think anyone saw me using those two rocks to terminate my ECU wiring!

Thanks for the threads!
