Relay Cable

Post by gfeing4935 »

When making a relay cable for a MS-II V3.0 board using VR, Low Impedance Injectors, and ignition coil control what pins should I ensure have shielded cable? And to what pins do I connect the shield? And can I use RG-6 cable?

From what I have read so far I think I just need to use a shielded cable for the VR signal (Pin 24) and ground it on the MS-II end (Pin 2), but I want to be sure.


What is the difference between RG-6 and RG-174 cable?


Thank You,
Greg

I think the VR wires are grounded through the edis modual, why not just buy the wiring harness for DIYAutoTune.Com for cheap they take the guess work out of these things.

Shield the VR wire, ground to pin 7 I thought, sensor to pin 24. I just used an old loom from the wreckers, cut the wires out. It was a Toyota loom and the O2 sensor was shielded too.
