Hello fellow Isuzu fans, looking for some help. Does anyone know anything about matching old wiring colour schemes to modern colour codes?
Am dcoing some work on old Deutz tractor(German) but colour of wires bit confusing. I have lots of stripy coloured wires - black+red, white+black, green+black, red+white, blue+black - but no solid colours except solid brown.
I'm wondering how to match these to modern colours. Does a stripy red+white wire correspond to a modern white wire or a red wire for
example? Confused

To be honest most manufacturers made up what colour wires they used on their vehicles depending what mood they were in that day. Well that seems to be what I have experienced. For example the speed sensor wire from the dash is light blue+red trace on Vauxhalls, but will probably be different on Fords.

Are you at the engine or tractor ? I know Deutz wiring fairly well, is it an aircooled one ? Browns will be the earth and the coloureds lives to items .

If you give us an idea of what your up to , renewing or upgrading ?

The wires will be a main colour with a smaller tracer colour for example - white with red trace is 99% times starter solenoid.

There is no handy way of matching up that I have seen to date .

Hello Gribble, yeah air-cooled D6806 agri tractor, mid to late 70s. All lights missing, headlights, indicators front and rear, parking lights, ploughing
lamp behind, even horn under bonnet gone Sad

Previous owner says it was gutted for some other tractor. So basically there are wires hanging
all round the place.
Got new light cluster for rear, four wires:black, blue, red and yellow on left side; on right side cluster have black, blue, red and green. Hanging from
where old light cluster was once upon a time I have on left stripy black and white x2 wires, stripy black and red and solid brown; pn right side I have
stripy red and white, stripy green and black, stripy black and red and solid brown. I need to match up new to old to give me indicators left and right,
brake lights left and right, rear parking lights left and right.

Old cluster Right: red+white New cluster Right: black Old Left:black+white New Left:black
black+green blue black+white blue
red+black red black+red red
solid brown green solid brown

And forgot to mention, front of tractor where indicator/parking light cluster used to be I have on Left solid brown, and stripy black+white wires x2; on Right Ive got stripy red+white, stripy green+black and solid brown. That old cluster held a 5w parking light and a 21w indicator. Previous owner said everything electrical was working on tractor except indicators, so suspect flash unit has gone.

Have got brake lights going this morning by connecting up new solid red wires with old black+red stripy wires. Blew fuse in process of elimination Smile

Will toil on after supper tonight.
