i recently rebuilt my 03 r53 engine. i currently have it along with tranny installed in vehicle and em trying to figure out the spegetti mess of wiring . ... i took some pics but they dont seem to be helping me to much. i know i know i should of marked the wires, well i didnt. if anyone has some good wiring pics from a rebuild ,they sure would be helpful. i will include some pics of my rebuild asap. thanks for anyhelp.

 

www.realoem.com has a diagram for just about anything for the mini

 

ive added some pics of my rebuild the first pic gives you a good idea wear im at with this mess.

 

anyone living near york pennsylvania with an 03 R53 that would be willing to let me look at their motor wiring would be a great help. i beg of you please help me get this beast wired.

 

Looks like a lot of work but nothing you can't accomplish if you've gotten this far in the process. I really like the green! i'm a big fan of a painted engine bay.

 

If I am correct most of the connectors only fit one thing. Start by seeing how far the wire run is and see if there is a plug by it to match up to.

 

thanks clay. its been alot of work and im getting impatient. looking at the wiring almost makes me wanna cry. i want to rout the wiring the correct way cause as you know its a sardeen can in there and chaffing will be a problem if i dont. i cant wait to turn the key!!!!!

 

you are correct bram . i dont wanna go under when i need to go over with a wire and vice versa. it might just be a trial and error process. thanks for the suggestion. all are appreciated

 

i really need a R53 owner in or near york pa. that would make it easy.

 

I will be in the area in 2 weeks if no one else helps by then.

Tons of new upgrades! So what sparked the rebuild anyways?

 

i had a stage two master clutch with aliminum fly wheel put in and it blew out in 2000 miles. by the way its a piece of crap clutch dont buy one . it threw two clutch disc springs out of disc and scoured badly the flywheel. when i bought the mini the guy who owned it before me put the 19% reduction pulley on the supercharger and didnt upgrade the fuel injectors and that results in a lean fuel condition. there was about 20000 miles put on the mini while running lean. that is the reason i pulled motor and trans and seeing as i had it all apart mite as well replace everything possible.
