Thread: starter wires. please help

  1. #1

    starter wires. please help

    So I tracked down the yellow start wire and ran the cable from the battery to the positive end of the cylinoid. I'm having troubles with the instructions telling me to splice 2 red wires to the fuse box. do I connect both of these wires to the positive end on the cylinoid? and where do the other ends of these wires go? there are two yellow wires in the fuse box do I cut those off and connect them straight into the fuse box? the instructions are extremely unhelpful lol.

    Okay. So I was looking through the instruction book for a pic of the fuse box hoping it would give me some indication of where it would go. There is a 3 pin plug with a blue wire a blk/wht wire and a red wire. It looks as though I would connect a wire from the positive end of the starter and connect the other end where the red wire is on the 3 pinned connector. Is this correct?

    What year donor did your wiring come from and do you have the factory manual with wiring diagrams?

    Its a 02 impreza. I don't have the wiring schematics. It will turn over if the ecu is disconnected. While it is connected the check engine light flashes and there are 4 or 5 relays all over the place clicking in a pattern and it won't turn over...
    I don't believe the car an alarm or anything like that..

    you can find the manuals here if you want.....

    http://ken-gilbert.com/impreza-manuals

    They provide info on anything you want to know and were great source of info to me. Including complete wiring info.

    The yellow wire goes to the solonoid spade connection.
    The double red wire they are talking about..... they are referring to the connection between the fusebox ring connection (bolt connection) which on my donor wiring went to the positive battery terminal.
    I mounted my fuse block and relay panel in the front of the shifter tunnel, so very short distance to the battery positive terminal.
    They are probably connecting it to he starter battery connection to save you the wire all the way to the front battery if you mount your relay panel where they suggest (near the gas tank).

    I have come to this point in my wiring and have the SAME question!

    Does anyone have pictures of how this is connected?

    Here is what I have of the red wires on the starter side and the fuse box side. The yellow attaches to the spade terminal on the starter solenoid.

    Thanks for the answer. However, I can't get the pics to open on my end? Can you PM me them?

    I truly appreciate it. Even though I mostly a lurker, EVERYONE on this forum, past and present, have definitely helped me with my build!

    Sorry about that. Images are updated.

    Well, I got a little over zealous in my wiring diet and eliminated the Trigger line (Yellow wire with Spade connection) probably thinking it was an airbag at the time. I dug it out of my wire box and connected it to the starter, can someone confirm where the other side of the trigger line (yellow) connects?

    Yellow line connects to the starter interlock relay (B105 on the 02-03 harness, B225 on the 04-07 harness).

    I am trying to make since of it too?IMG_2404.jpgIMG_2405.jpg
    When I took the tape off my harness the positive battery terminal with a ground for the fuse box came off with no other wires connected to anything else, so if I connect it like picture 1 it goes to the starter (is it on the correct connection on the started pic 2) Then does the yellow wire with a spade give power to other parts of the car? On the pics attached in post #7 is the black / yellow wire that becomes 2 red spliced wire the ground or did I orginally mis-label them? What is the point of taking 1 wire and splicing it to connect both to the same terminal? Do I have it backwards and on picture 2 on post 7, the big red wire goes to the positive terminal and to the battery and the 2 red goes to the ground? Is this making sense?

    In picture #2, You should NOT have any wires or cables attached to the bottom post of the starter solenoid.
    I connected the negative cable from my battery to a bell housing bolt holding the starter on. Then uses a ground strap from that point to the frame near the motor mount.

    So since the battery is now up front and not next to the engine in the donor, things will be changed. Currently the bottom post has the black with yellow stripe wire that goes to the negative battery terminal and to the black fuse box, Am I correct that the black / yellow stripe wire is a ground wire? There is no color designation on the wire schmatics. Are you saying to ground it closer and then up front the battery will have a ground for it up there too.

    The bottom post of the starter should not have anything from the harness connected to it. It only connects between the starter and starter solenoid via a very short built-in wire.

    The large black/yellow should be attached between the battery negative post and chassis. Your engine/starter will then ground to the chassis with the woven silver strap included in the kit. It's typically recommended as well to run another heavy duty ground cable (not supplied with the kit) between the negative battery post and the engine/starter as a redundancy.

    IMG_2444.JPGI figured out the ground wire, thank you, but am still confused on the red wires. 1 comes from the positive battery terminal to the starter and the other red goes from the starter to the fuse box, where does it go at the fuse box? The 2 pictures in post #7 on my car are a black with a yellow stripe which is the ground wire? I attached picks of my fuse box and a pic of the old positive battery cable, wondering were the second wire connected to on the fuse boxIMG_2443.JPG
