I was originally told, shortly after buying my car, that all wiring on Mk2.5’s included all wiring necessary, - advice I’ve been acting on for years.In this last two years, that advice was not entirely true, as while some looms have all wiring in them, interconnections are often missing between one loom to another. Take the dash wiring loom as an example, it appears it does contain all wiring associated with any switch or other device fitted to the dash, which is terminated at one of several ‘common connectors’. THe main fuse box (under the dash) for example has it’s own common connector, which means all fuses are provided in the fusebox for any additional requirement, but the connections between it and the dash loom are made between it’s common connector to the main dash loom connector via add-ons, usually made at the factory.
So the dash loom contains front fog lights, which were only fitted in early models to Sport models, so in that case connections were made between the dash loom, and another feeding the engine compartment. Not sure this holds true for all Mk2.5’s, as I have enough problems with the heated seats, however, if anyone wishes to know, I can take a look at that in the manual. (Later!) I do know that wiring extends to connectors which still require a short cord for the actual fog lights - as that’s shown in the manual.
Andrew at Autolink did kindly give me a part number for a works loom to connect between the main dash loom connector (X05) to the heated seat switches, but as he gave me two part numbers I’m unsure which is correct for an NBFL. Apparently this loom contains a pin for each of the four wires that plug into X05, so makes the work easy enough.(X05 has empty spaces where the additional pins fit) BUT - I have doubts about availability now, seeing as the model is between 13 to 17 years old, and I wonder what stock is left on Mazda’s shelf. Also time delays, anything in stock at the European depot (which take up to a fortnight to get to a dealer) and will take even longer if ordered from Japan - that’s for sure. If there’s not one left, then it needs a special order placed on an individual supplier to have one made, and that will certainly double the cost IMHO. “One-offs” aren’t cheap.
Anyone chopping a loom out of an old car - along with switches and seats, isn’t going to think about pulling the pins out of connector X05, so will probably cut the wires away from the connector, leaving the pins still inside. That makes connector more difficult, so anyone doing this from scratch has to connect the new wires to the relay base wiring, which is what I’m presently thinking of doing. However, if I can locate a source for these pins, then the fitting job becomes a lot easier. This is the type of info that’s elusive to find,as are part numbers, relay ratings etc. - none of which appear in the manual I have.
At a quick guess, there’s already several owners who asked for advice, and based on information given to start with, and what is visible in the manual, I told them all to look for a four pin connector behind where the seat switches fit, so until recently, I gave up, as most appear to have used the Nutz info to add the wiring themselves, ignoring the fact that the OEM wiring is 80% still in their cars. This way also ignores the fact that thore are two separate fuses involved, and advises tapping off the Cig. lighter instead.
Another version I read some time ago states that the headlight circuit is a good supply, obviously not thinking about cold winter nights, when you may need both at the same time!
