New engine loom

Last time I rebuilt the engine I bought a generic Duratec loom from SBDev. Very nice quality and well made loom. But as it only had wiring for controlling the engine and not for fans, starter relays, dash gauges etc I made my own loom for that.

It worked fine but it looked like crap. Now when I'm waiting for engine parts and have nothing better to do I decided to do it again but with some more effort this time. I also wanted wiring for a few more sensors to the ecu and a future data logger.

The new loom have these connectors:

• Starter solenoid
• Starter relay
• Water temperature (dash)
• Alternator warning light 
• Fan 1
• Fan 2
• Fan relay
• Oil pressure sensor 
• Oil temp sensor 
• Fuel pressure sensor (future)
• Data logger (future)
• Chassis connector 
• MBE 1 (existing connector on engine loom)
• MBE 2 (new)
• +12
• GND

I started by doing a template with some wire, tape and zip ties.

Then the actual wires.

Lots of heat shrink tubing, and some of the connectors

And here it is!

Heat shrink tubing, the best since sliced bread

I haven't tested it in the car yet, but what could possibly gone wrong? ;-)
