Wiring harnesses nightmare

I've had an absolute f**king nightmare with this but my 2 year old showed me wot was wrong!

Getting the re shelled rot box ready for MOT and the hazards didnt work stripped out the dash to find some fanny had wired all his extra lights, boost gauge etc. into one tiny wee black earth resulting in the harness melting together! Didnt want to take a chance and repair it so made the decision to change the harness from my sunroof model to the new umbrella model. The harness goes behind the dash and has the fuse box on it! Nightmare! Anyway, got it in and went to fire it up..........nothing! My two year old son then decided to turn the headlights on without me knowing, i turned the key and....BOOM she fired up! Boys a fuckin legend! Hahahaha anyway turns out the harnesses are different! The large multiplug is wired slightly different meaning the back lights and fuel pump feed are switched so i'll be changing the other harnesses over today.

Dont know if this is common knowledge but might help folk trying to reshell a car like me. Be aware chaps.

yep theres a few variations between phase 1 and 2 wiring looms
why they never left them the same I really don't know

Haha your 2 year old is a future mechanic right there glad you found the issue tho

Same thing happened me too.
Wouldn't start unless lights on.
I forget what I done but she ok now.

Swapped the rest of the harnessses over today and it fired up straight away! Everythin works even with the lights off! Yaaaaaaaaaaaaaaaas! The wee man was turnin the lights off and on expectin it to cut out! Wee wide-o! Hahahahaha

Suppose i could have ran a relay for a battery live to the pump but it just wasnt right and would have annoyed me! Ha
