Alright as I've posted before I have serious wiring issues with my crx as in my injectors are run with like speaker wire lol.
1st question I have a 99 d16y8 in my 88 crx which means I have an obd2 motor in a obd0 car and I have no idea how it is runnin but it runs great just CEL and no vtec but anyway I was thinking. Could I take a obd1(95 civic ex) harness and a chassis jumper and a ecu jumper and run a p28 ecu
But to do that I would have to convert the motor to obd1 what needs to be changed to make it to obd1?
2nd question previous owner put rear disc brakes on the car it seems as if they ar DA brakes but I am not positive I know it has drilled slotted rotors and rear discs lol anyway when I step on the pedal and drive for a bit they start to drag and eventually start locking all 4 of them lock up and they hold the pressure until I open the bleeder valve on one of the calipers to release pressure.
The master cylinder is a crx si unit
The prop valve is a crx si unit
The brake calipers are rebuilt and as I said I believe they are da brakes
The booster is a crx si unit and is rebuilt
The brake lines are brand new
What could cause this I don't know what to replace or if something needs to be a da integra unit or something I'm totally lost all help is appreciated
Thanks in advance

If it was the cable would it lock all 4 and would I be able to release the pressure by bleeding if it was the cable it would just stay locked and drag all the time right?

releasing pressure by bleeding wouldn't do a damn thing if the cable were "locked" or "dragging" and it would only cause the back brakes to lock up or drag and not the fronts.

Rywire.com is a good place to look for wiring, even if you don't have them make your harness the website has good info.
There's also good info in the FAQ

Thanks for the help its hard for me to search I haven't put it in my sig on this forum but on others I have it cause I get on honda tech via my sidekick and this bitch sucks haha but thanks for thehelp ill look it up and rywire has already helped me I told the my issues they told me t send them my current engine harnes they are gonna repair it and set it up for my motor where it will be plug and play al I have to do is wire my vtec to my vafc and coila
sounds a valve is getting stuck and turned itself into a 1 way instead of a 2 way. I'd try the master first. get a junk yard one for cheap. if that doesn't work, try the prop valve. good luck man and keep us posted!

But a DA integra master cylinder or crx master cylinder cause the crx master cylinder is new and the prop valve came off another car that had working brakes thatis why I was thinking I needed a 40/40 prop valve and a da mastercylinder/booster
