After all the endless issues with starting and running I took the plunge to make a new engine loom.


pre_layout

Measuring the sensor layout and route I transferred this to paper, the ecu bottom middle, and the sensor plugs at each position. Each place has the cable colour, the plug pin number and then the ecu pin number. Loads of prep work made being confident with each cut easier.

The cables were laid out, and cut, each joint soldered and covered with heat shrink.

The loom was finished as below, and then tested in the car for fit before wrapping in plastic trunking,. not the neatest, but, and a massive but, it now works

Now to re-wire the whole car.

might take a little longer, especially when finding odd things like a 10v regulator that's not on any of the wiring diagrams,. and the fact that all the wiring is pink or yellow!!

Nights in the garage coming up

I do find making a good, neat, and well made loom very satisfying

I'm about to do my own loom for the first time and I just wanted to ask if there is a standard method of wrapping the wiring?

I've got a flying loom from the ECU manufacturer to start me off. My plan was heat shrink first and then some fairly loose rubber tubing/piping on top, with insulating tape at any junctions and maybe cable wrap in exposed places.

Does that sound ok?
