Rembrant Posted July 20, 2021 Share Posted July 20, 2021 Which pigtail fits the BRMC63? I don’t know if you can buy it or not. I don’t see it on Rock Auto. I grabbed a couple at the junkyard, one to install and a second for a spare. There are three wires, common and n/o and n/c. I have mine set up so that the low fluid level will make my Brake light come on. Link to comment Share on other sites More sharing options...

I really need to dig in to the parts catalogue, and that's a challenge on my phone. Link to comment Share on other sites More sharing options...

Digging a little deeper I find that Motorcraft Wiring Pigtail #'s WPT1001 and WPT446 seem the same and are used for many things. Inertia switch connector, automatic temperature control, tailgate lock, brake warning switch, ect.. In the aftermarket we find: Dorman 645-920 Auveco 23180 Carpak 96-7552 Wells 870 Airtex 1P502 AutoZone 1P1502 Carquest 57-5283 Link to comment Share on other sites More sharing options...

Thanks for your help. I'm now going shopping... I picked up a master cylinder @ upull off a 93 F100 with a 1 1/8" bore, the BRMC 63 is 1 1/16". Will the difference make braking harder, or easier, or will you be able to tell the difference? Thanks, Bill Link to comment Share on other sites More sharing options...

So I think you'll have to press down harder to get the same stopping results. Link to comment Share on other sites More sharing options...
