DIY CAS wiring...anyone know how?
Hey guys,
Im needing to wire a cas from the ecu back but I dont have the entire shielded wiring so I was wondering if anyone knows how to make shielded wiring without having to purchase expensive hard to find pre made 4 wire shielded stuff???
Can I wrap it in something thats easy to find at a say a radio shack???

Ghetto way to do it: Take a coaxial cable (you know, TV cable) and cut a slit through the outer insulation layer all the way down the length you need. Strip the insulation all the way off. Take the 4 wires and run them in 2 pairs. Hook each pair to a drill, and tape the other end to a table. Run the drill until wires are neatly and uniformly twisted, repeat with second pair.Now, take the wires and tape one end to the inside of one end of the coax (the white insulation, leave the steel braid alone. Now all you need to do is slide the steel braid all the way down the length of the new wire. Wrap it in some friction tape, or convoluted tubing and you have a shielded double twisted pair wire.

Twist each vr sensor pair of wires together the entire length. Putting the two ends into a drill and squeezing the trigger is an easy way to do this.
Then, slide over tinned copper shield. Make sure to crimp on a wire to the braid at the ECU end, and ground that wire. Make sure you ground one end only of the shield! Then, slide heat shrink over the entire length and go at it with a heat gun.
This is the sheild I use.

If you can't find small quantities of shielded 2 pair from your local electronics store, try a music store. Double shielded 4 conductor microphone cable is a fairly standard item at most music stores and sold by the foot. It's rugged stuff as it is designed to be tossed around a stage. Just make sure to use some split-loom tubing and wrap it properly to keep engine bay nasties out of it.

You can get away with almost anything on an n/a, but imitation CAS wiring is just asking for a blown motor on a turbo car. Sure there are sources of wires and there is advice from experienced people on this site. But what if you don't get it right the first time? Are you willing to risk a motor? It happens all the time with Haltechs. There is no substitute for the fitment and engineering of OEM wiring harnesses provided that they are not 100% completely cooked. Heck, even a mediocre condition harness is going to work out better as long the connectors still work, the grounds are clean, and no insulation on the wires has melted off.

Yes, by the linear foot. I guess this would have been the better link.

I've tested resistance on my CAS numerous times and it's in spec. I swapped a known good CAS and the car ran wonderful for about a day...then went back to running just like the CAS I had removed. I've tested both CAS and they both test within FSM specs. Next step is reading up, testing the engine harness, reading threads like this on DIYing the CAS wiring.
I have numerous issues going on so I'm sure the CAS isn't the cause of all my problems...just one area to focus on. I'll be keeping an eye on this thread, hopefully it can point me in the right direction with my own issues.

I just hopefully confirmed that you have to crimp a ground wire to the cas shielding...man I've asked this over and over...
