having a few a PM's asking about the ecu/fusebox relocation so thought id post up a guide,
havnt got many pictures unfortunately because at the time was just focusing on getting it all done and built up ready for work on Monday haha:panic:
this can be done with the engine in still in but will be a fair bit more awkward , it is a lot easier with the engine out ! this is based on my 2003 3 plug 16v'd quicksilver - different cars/models/years will have slight differences
so whats needed:
. all tools to remove the engine ( if you go down that route )
. a spare donor wiring loom
. soldering iron
. solder
. flux
. cable ties
. a shit load of heat shrink - got like 7meters worth off ebay for about 1.99!
. and some of this to make it look prettier - http://www.ebay.co.uk/itm/Wiring-Loom-Cloth-Harness-Tape-19mm-x-25mtr-Roll-High-Quality-Adhesive-/221360583733?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item338a1e7435
right so what I did:
. removed the complete engine with gearbox and loom all attatched ( already a guide around somewhere for that )
.remove the arch liners
.remove glove box
. right now leave the engine etc to the side for the time being and move onto the bay, you have your fuse box on the right hand side, I think it was a couple of 10mm/nuts/bolts that held that in place, get rid of the plastic shit and you are now left with the fuse box its self with all the wiring, unplug it all and go to where the arch liner was and pull all the fuse box wiring through and into the underside of the wing if that makes sense?
. now if you look up towards the door you will you see a massive plastic grommet that the interior loom runs through, 2 or 3 10mm bolts/nuts hold this grommet in place , this is where you're gonna run the wiring through and that is right behind the glove box
. also the big multiplug/small plugs (depending on year) disconnect this from the car and pull that through and into under the wing and leave that there, now all the wiring that needs to go to the fuse box needs cutting and extending , take your time and do it a wire at time to ensure everything goes to where it needs to go! once done feed it through the grommet hole and into the car , now you can plug your fuse box back in, also you have a live that goes there , obviously this wire too will need extending
. and now onto the engine loom, what I did was get the engine to a comfortable height to work on ( as this is gonna take a good while! )
you want to have all the wiring loom plugged up etc on the engine and gearbox and lay the rest of the loom out as if the engine was in the car if that makes sense?
now the daunting bit, take off all the protective plastic coatings and shit like that , but as you do cable tie/tape all the wiring in one spot to keep it together
once you have all the protective shit / tape off sit down and have a brew/fag as it is a ball ache!
right what some people do is leave the wiring loom where it is and just cut and extend each wire for the ecu , but what I did was once all the wiring loom was stripped down was grab all the wiring for the ecu and fuel relay and bring it all over to the gerbox side if this makes sense?
tape it up in a few spots now just to keep the appropriate wires together
so what youre aiming for is to make the CURRENT wiring for the ecu to make it long as possible , and to do that you will have to cut and extend some of the wiring for the sensors! rather than cutting and extending about a billion wire for the ecu :drink:
. right so now you have the ecu wiring to the gearbox side you now need to deal with the wring to the alternator as that runs on the same side of the engine as the ecu, so bring all the appropriate wiring round to the gearbox side, cut and extend what needs extending and feed the wiring to the alternator/oli pressure switch etc behind the exhaust manifold . make sure its tucked well away so it doesn't get cooked!
I hope this makes sense so far? just wish I had taken pictures :wall:
. ALSO once you come to cutting and extending the wires make sure to do one at a time so you do not get confused as you will have a pile of spaghetti wiring and you don't wanna get confused and be sure to make sure you have a good connection once joined up as you really wont want a broken wire somewhere once its all built back up as that will not be fun to find!
. when eventually everytyhing that needs to be extended is extended and everything is where it needs to be secure the wiring together, and by that I mean but a cable tie/a bit of tape round the apportpriate wiring for the ecu to keep them together, and do that for each bit of the loom like for each sensor etc keep the appropriate wires together!
. once you've done that pull the loom off the engine and lay it out on the ground, making sure everything looks okay, once youre satisfied everything is okay go ahead and tape up the whole wiring loom with that tape that I have linked above! it is so much better and neater looking than the normal insulation tape stuff!
once that's done feed the wiring loom through the gap by the bulck head where the trackrod arm/end go through if that makes sense? and join up the mulitplug(s) there, and now since you have rearrange the layout of the loom you should have your ecu plug(s) there too and it now should be long enough for you to feed through that grommet and into the car, now you need to secure the wiring and it is very very important to make sure the wiring loom will not rub through anywhere, so what I did was use bits of that old plastic casing shit that you took off earlier and wrap that round where the loom touches chassis
now fit the engine and plug all the wiring loom to the engine , once all the earths/lives/plugs everything is all where it needs to be you can then go and see if it starts!
if you do it carefully and take your time with it and do a wire at a time there should be no reason for it not to work as all youre basically doing is just rearranging it all , be sure to give your self plenty of time too as it is very very time consuming and not rush it all like I did as it had to be back on the road by sunday night and started on it Saturday morning :wall:
im sure there will be bits i have missed but when i think of them i shall add them on!
and I do apologise about this mahhhhooooosive wirte up but I hope it is of some help to others and apologise too about the lack of pictures! but do have a few random ones!
