    Default help help help modifing a sr20det loom

    hey people
    for all those people who have put a sr20det in there sprinter and used the s13 wiring loom and computer I NEED YOUR HELP.
    all i need to no is how you modified your loom and witch wires are used to power up everything. all i no is all the wires needed are the 3 plugs at the end of the loom on the left hand side and the small white plug next to the ecu. any body have a step by step guide for wiring itl its going in ke55 but a sprinter guide will be fine thanks all.

    ok heres my effore of coppying my diagram lol its looking at the ecu plug, there is a heap of shit u can cut out leave the white plug on as i found out it is required to do a remap.

    think its the light blue wires are all ambient temp sensor junk there is 2 sensors over boost and the like that are not required, i do have the diagram so u can chop out all the crap but cbf including all the wires on my diagram.

    will run without o2 sensor knock sensor, have taken out all the idle control stuff ( mounted on the manifold) and all asociated wiring and will run fine without it, there is 2 plugs which mount down under the pasangers headlight in an s13 that have a massive ammount of wires that you dont need but do house the fuel pump wire and a couple of power wires!!

    hey fast eddie so all those wires that need power is it a good idea to relay each indervidualy or seriously get all wires that require power and run them to 1 relay and use ignition on to trigger it.

    and is it true there is a wire that connects to the start wire of ignition barrel or the strt wire that goes to starter motor

    thanks guys

    i put a + next to the wires that need to be conected to the battery and explained what the other ones do, the ones i put in there are the ecu ones that need to be connected to make it run!! the start one is the orange wire and just needs to be connected to posative, i use a 4oa relay with 2 pin outs and just evenly put the big wires and little ones on each pin!

    Eddie's way will work but he makes no mention of which ones go to batt and ign. One dude on here said that they can be funny if the the relays aren't wired up properly so I wired mine up as nissan did. I never did try wiring everything that needs ign power off relays so I can't tell you what the result is.
