Have i got the wrong loom?

[Sparticus]

Hi guys need to know if i've got the wrong loom...have 2 brown wires (one with a yellow stripe) coming from the corner of the wing and also 2 white wires. also at the same point i've got a bundle of 3 different wires.

Have included a pic. BTW its a Chevy engine i've got.

You should have got a few pieces of paper with all the colours listed and where they run from and too. If not I could scan mine

I think the brown ones are the alternator, white ones are to the ignition coil or HEl +ve input.
The other 3 may be water and oil sensors but without the colours don't know for sure.

Update: the three branches of wires coming off at the corner of my inner wing are as in the pic above:

1/ White
White + Yellow
White + Black

2/ Brown (approx 5mm thick)
Brown + Yellow

3/ Blue + Dark Green
Light Grey
White + Brown

None of the above wires end in terminals (except the white, white+yellow, White+black)


Theres a big wire also (coming off the black box thing i've fitted above the transmission tunnel). On it is...

4 brown wires finishing in a ring terminal
White+Yellow
White+Red

1/ White = Ballast resistor or +ve input on HEI Distributor
White + Yellow = Ballast resistor or coil to start solenoid to give 12 v boost whilst cranking with a 6V coil. (not used on HEI distributor)
White + Black = coil to rev counter

2/ Brown (approx 5mm thick) = Alternator main output
Brown + Yellow = alternator to charge warning light

3/ Blue + Dark Green = water temp sender to gauge.
Light Grey = Oil temp?
White + Brown = oil pressure switch to warning light

None of the above wires end in terminals (except the white, white+yellow, White+black)


Theres a big wire also (coming off the black box thing i've fitted above the transmission tunnel). On it is...

4 brown wires finishing in a ring terminal Same connection as main battery lead on starter solenoid

White+Yellow = other end of white and yellow mentioned above

White+Red = Starter switch to start solenoid.

I have attached the document that all these colours come from.

so have Dax sent me the Ford loom instead of the Chevy?

Looks like the chevy loom to me.

I had to modify quite a lot of this as I removed unused wires such as the starter to coil lead as I used an HEI distributor and I used all mechanical gauges so removed all those wires too. I also added an ammeter, Central ignition key mounted in the dash and a start button.

I also found that some wires didn't come out the main loom n quite the right place. It is a simple enough to unwrap the loom and route them where you need then re-wrap the loom again.
