Wiring Help

[BeingOriginal]

As part of the winter tidy up I’m having a look at the wiring in the car.

To give some background the car had a new crossflow loom plus scholar engine loom matched to a dash2 dash when it was rebuilt, it has no screen and a very simple dash layout and as such there’s quite a lot of redundant wiring. My aim is to remove everything unnecessary, put a couple of neater solutions in place for things like resistors and also fit a lambda sensor.

I’m not 100% confident with wiring (keen to learn more) but wanted to know what others have done, I’m happy to pay for someone’s time or find a recommended mobile automotive electrician to go through and check everything if that’s the way to go.

I’ve already resolved some obvious things but below are some examples of things I still need to sort.

300ohm resistor to allow dash to read signal

Sorry to be pedantic but that looks like a 33 Ohm resistor, orange, orange, black.  The silver band means it's 10% tolerance.  330 would be orange, orange, brown.  On a four band code the third band is not a number but indicates the number of zeros after the two digits.  With five bands the first three bands are numbers, the fourth is the decade multiplier and the fifth tolerance.

See here for more info.

Apart from tidying up the wiring it's really helpful if you document what you've done and, where there are any components buried in the loom, their type, value, function and location so, when you come to fault find you won't have to try to remember what you did.  Photos are good too.

Well worth removing the scuttle if not already off.

Good luck

Thanks for the reply Paul

Resistor is definitely brown but clearly hasn't photographed well.

car is fully dissembled and I’ve been photographing and dynamo labelling everything as I go, it was my fear that I’d never be able to fault find an issue that started the project!
