 Automotive wiring kits           


Hot Rods, Customs, Street machines, Car re-wires




This kit has been designed by an auto-electrician with 20 years experience. After trying to install another wiring kit supplied by a customer into a hot rod, we realized how inadequate the wiring kits on the market are. It is because of this, we have gone about designing and building our own wiring loom that comes pre-wired to a fuse/relay box, with no need to add anything else. The automotive wiring kit includes everything you need to professionally re-wire a car. As well as the loom being properly wired it is by far the easiest kit to install because all the circuits are complete and already run to where they will approximately finish up. The loom comes clearly labelled where all wires go and the instruction booklet gives a colour code breakdown of each wire, its location and explains how it is to be connected. As well as the instruction booklet there is an installation DVD included, to guide you step by step through the whole job (with handy tips included). All you have to do is tape up the loom, fit it into place, cut the wires to their desired length and join them up. It really is that simple, a very painless process.

        There is a choice of two kits, one is for a Fuel injected engine, although the engine management harness is not included it does have wiring included to connect to and run the ECU and engine harness. This connection allows the ECU to run the thermo fan, fuel pump and has speed sensor, start and tacho signals present. The other is for a non EFI engine.

        The main feature of this wiring harness is that all the circuits come professionally pre-wired. This makes this wiring kit the most painless on the market to install.

        Along with all fuses, there are 2 circuit breakers, again installed and pre-wired. One for headlights and the other for heater fan and electric windows.

        Included as well are two flasher cans installed and pre-wired one of them for Hazard lights and the other is an electronic non load sensitive unit to ensure an even flash rate of the indicators, no matter what lights are fitted even LEDs.

        There are headlight sockets and fusible links supplied in the kit

        The kit comes complete with terminals, 2, 3, 4, 6 & 8 way Q C connectors, eye terminals, individual terminals and rubber grommets

        The kit also comes with an Installation booklet that runs through every section of the loom as labelled on the wires and gives a description of each wire, its colour code and what it does.

        All the earth wires are wired into the loom and run to three common earth points. (other kits donít include any earth wires)

        The fuse/relay box is set up to be mounted on the passengerís side of the dash, where there is generally more room to mount it up out the way.

        Only quality wire and accessories are used.

        The whole kit is posted out to you and in most cases postage within Australia is under $30.00

        The kit comes with a phone number that you can call for advice and speak directly to a qualified auto electrician.

                    Best of all the whole kit is 100% Australian made.

Optional extra


   We are offering for purchase a Crimping tool that crimps both insulated and non-insulated terminals. The crimping tool is not the top of the range because the best crimp tools are generally ratchet type crimp tools and retail for around $80.00 each and they only do either insulated or non-insulated terminals not both. The tool we recommend can crimp both types of terminals and retails for approximately $95.00 + GST we are offering it at a discounted price of $88.00 including GST to help ensure a good standard of connections for installing you new wiring, and in turn less problems as time goes on.

 Please advise us when ordering if you would like to purchase a crimping tool as well.

For cars with an electric fuel pump, we wire them up to be able to be connected directly to a Gas Safety Switch to operate the fuel pump relay. If required we can supply the gas safety switches for $77.00. This is a good safety feature and strongly recommended.
