    I'm not sure where the dizzy kit came from as it was bought second hand off the forums... Ignition + in the ae111 factory loom also powers the o2 sensor, iscv valve and the evap thingy that plugs in under the throttles so be mindful of that if you use new wires.

    Follow most of the 4age, had to extend only a few wires, the ignition and o2 goes along the AC pipe area though.


    Vinyl tape (no sticky goey stuff and more like oem)




    Crimps ftw

    What did you do for the connector on the firewall? I pulled them up through conduit near the diag box and connected it like factory... In hindsight it might have been easier to make a "seperate" loom for them and deleted them from the engine harness.

    I'm definately going to buy some of that vinyl tape, looks a million times better than electrical...

    vinyl tape is awesome, retains loom flexiblity, and its automotive grade. Was difficult to locate since its real OEM equipment and usually can't get in small quantities but I managed to find them from pentastarparts.com.au, just use heat shrink at the ends to keep them from unwrapping.

    For the firewall connector, I ran it like a kouki style loom - part of the dash loom - running to connect to the engine loom, for a cleaner engine bay.

    Are you running the heaterbox at all?
    If not, I found that the easiest way was to run the loom through the middle holes where the heater pipes would go through. Then make a neat little loom to go around and branch off the engine. Makes for an almost wire tucked look.

    I reckon make the loom run up to the wiper hole everyone is directing you to, then chop it and put a plug on. Then make your own loom to go around the engine bay, gets rid of the need for extending it and also makes running the wires easier.

    Ya heater box is in, im going to tinker with the loom a bit more and proberly go through the a/c hole. i dont like to solder as it breaks from vibrations over time, but i have got two male and female aircraft cannon plugs from work which i might use to extend the loom. ill make my executive decision in the next few days.
    Really appreciate all the input tho guys.

    Soldering is usually only a problem when not done correctly.

    Form an x and twist each half tightly and solder over the top, then heat shrink or tape. The thicker the wire make a bigger x. And buy a high wattage iron as it makes the biggest difference

    Matt's on the ball. Soldering is fine, I've never ever had a break in a soldered joint. The only breaks I've seen are from a cold solder joint.
