Default What does this wire do then?
I have a question regarding the wiring loom on the cosworth.
I had a bit of a fettle with the cps plug, loom side, to increase the contact tension. It didn't cure my mis-fire, but it did have a lessening effect.
So, I'm pricing up to completely replace the whole lot for new, maybe reusing the plugs, maybe not. I'll have to see how I get on unpicking the terminal ends.
The question I have is, There are 2 tri-core wires in the loom (if my memory is correct). 2 normal looking wires with the third unsheathed and wrapped around the other 2 under a larger outer (black) insulator. For the map sensor and the knock sensor I believe. What are they arranged like that for? Can I get away with using 3 seperate wires for replacing them, or do they have some kind of emf effect, or insulating effect for which I'll need to either re-use them or replace like for like??
Also, what grade of wires should I be selecting?
I'm looking at some 16 Strand Copper Conductors - 0.5mm2 11amp rated, which I think should suffice for about 85% of the thirty odd wires that come from the ecu. Am I right in thinking this?
what other grade and rating wire do I need to complete the loom?
