Hello all,
I am planning on building a fancy new stripped back loom for my car with deutsch connectors etc. it's early days currently but first things first I am trying to assemble a list of the essentials so I can start planning my loom, I will then mock it up in string using the car before pegging it out on board and building it correctly.
I don't have the car at my flat so only really get to work on it etc. at weekends currently so was hoping for a little help, first things first I will be building an engine loom with bulkhead connector so I am after a list of engine sensors/powered items, I can then find the current draw of each and spec suitable cable etc. I am planning on a new fuse box inside the car populated with circuit breakers and new relays, so the engine fuse box will be relocated.
My car has ME221 and ITBs along with a coolant re-route, air con delete and by the time I do this PS delete also so most of the inlet wiring will be deleted along with the fan switch, PS gubbins and AC, off the top of my head (and no doubt missing many things) I so far have:
Power: Alternator Starter Injectors Coil
Sensors: Coolant temp IAT CAS (to be wired in scn twisted pair) TPS Wideband Oil pressure Brake fluid level
Potential additions: Oil temp sensor COP set up (from 1ZZ-FE?)

watching this with intrest as I'm intending to re-wire my car - admittedly just the engine electrical system and keeping the 'car' as Mazda built but with a few bits removed theres many ways to wire a car, but before you buy anything plan where it is going to live anyway. is the me221 the pnp or the stand-alone? if youve yet to buy then I'd suggest the stand-alone as it might have more features and allow a diferent injector / coil wiring solution (the NA 1.6 cars had banked injection not sequential & theres something in my mind about the ignition but I cannot remember ) as to COP, you can use Denso motorbike coils (I have a Triumph Daytona 600 & these look like they could fit ), these have the advantage of 2 wire connections not the 4 wire (or 3 if not using taco output) of the Toyota corrola / yarris Denso coils what sort of bulkhead connectors are you thinking of? Rich.

(the NA 1.6 cars had banked injection not sequential & theres something in my mind about the ignition but I cannot remember ) Probably a dumb question... but what are the differences??

What sort of bulkhead connectors are you thinking of? Rich. I have a PnP me221 from nearly 4 years back (I initially guessed 2, time flies!) so I am restricted by that in terms of injection I assume. This should be one area I can dive straight into, I build looms and other electrical thingys for a job so no excuses not to have beautiful concentrically twisted looms. Connector wise I was planning on using deutsch autosport connectors, manufactured by TE who also make the wires, twisted pair and heatshrink I was planning to use-one stop shop. I am also thinking I'll stick a remote battery post in the bay for starter and alternator duties. (the NA 1.6 cars had banked injection not sequential & theres something in my mind about the ignition but I cannot remember ) Probably a dumb question... but what are the differences?? I believe banked injection fires several injectors at once, then as the valve opens relies on the air flow to pick up and move the fuel into the chamber. Sequential allows individual injector control so the injection can be timed with the cam/valve and inject fuel at optimum time to allow it to mix with the air moving into the cylinder.

Ah, I seeeeee... I guess optimized individual injector operation means improved mixture, the ability to create a more controlled burn with whiz-bang flow dynamics analysis, and better mpg etc. etc. - which would be nice, as 30mpg is about my max... lol

Last night I replied about the injection, was a lovely long post then somehow I was booted off & logged-out Ffs. Anyway, ^^WHS I’ve a ‘spare’ standard na6ce front loom that i’m Intending to pin on a wall in my unit and then dissect the ‘extras’ including the ecu section, wonder how tangled it is Rich.

If it was an option I think it'd definitely be worth persuing, reading online seems to yield mixed opinions as to the difference that's actually likely to be seen in terms of figures.

First things first I will get it running again, then a scoure of the bay to see if I've missed any sensors etc. Work out how many cables are required per sensor and what can share common feeds, then spec connectors and source any new OE connectors I need, I am half tempted to pot the OE connectors and add flying leads to things but I am also aware I am getting hugely carried away with it all! I do love an excessive project though... A rope loom mock up will follow, and then finally a proper stripped back loom. I'm intregued about how much weight difference there might be between the new and original.

Any updates?
