Front wiring loom fun





Now that the engine has been installed it was time to start the front wiring loom, this was laid into rough positions, and then the tedious job of removing all the elctrical tape and covering from the loom, as the old stuff was removed i placed rings of electrical tape around the wires to keep them in position, once every thing had been removed i could then start the job of removing the wires that are no longer needed. the main ones for me to cut out were:
Air conditioning system
Head light lifter motors
Power steering system
Heating system
Audio system.

now this became the most time consuming part of the build to date, as the loom was removed from the MX5 i made sure every thing was labled up and i could decided what needed to stay and what had to go, i started by cutting off the connector for the no longer needed item and then tracing the wires back to the origin, either the switch or the fuse box, after about 6 hours of cutting i had removed the bulk of the wires, i have also done the changes to the loom such as wiper motor, adding additional wires for the new brake light switch and for the brake fluid warning light. once the wiring loom was all cut down, it was then covered back in elctrical tape.

now i came across the slight issue in that the lights front and rear come with looms that have water tight electrical connectors fitted to them, now currently with the modified mazda loom i just have bare wires and nothing to connect to them, now i did not want to have to solder the wires in, as this would cause problems with the front loom and the headlights, where you need to get the wires through the scuttle panel once that had been fitted, so i made a phone call to Ian at westfield and explained the problem to him, he then put a bag of connectors in the post, and were promptly fitted.

One of the IVA requierments is now that all of the loom needs to be covered in plastic convoluted tubing, well westfield only supply you about a meter of this which is no where near enough, so i made a visit to a local motorsport factors and picked up about 15 meters of tubing in verious diamaters, to cover all the loom and fuel lines. every thing was then covered and once i was happy with the location of every thing i removed the loom, to get it out of the way whilst i concentrate on other items.
