Mazda MX-3 All Motor Build
- Thread starter Allmotormx
- Start date
The harness was just going to be a clean up at first as im no electrical expert (new loom, remove vris sensors etc...) but once you get all the loom off and really take a look at it all it really isnt that hard to design a harness the way you want it. Ive made good progress on it so far by removing every sensor / connector thats not needed and just ran some rope through the engine bay to plan out the new layout. Ill post pictures as i go.
Sorry not much news on the motor as of yet but I am making some good progress on the engine harness project. I deleted a ton of un-used connectors / sensors at the ECU pins which really made the harness a lot easier to work with as now I am down to only 14 connectors off the ECU. I had planned on splicing the harness into a bulkhead connector into the firewall but after a bit of research it turned out to be a lot more costly to do this than expected and with only 14 connectors now I scraped that idea. Picked up some loom called ''Performatherm'' at a local parts store and it looks like it should make a pretty good harness material. I will use some Raychem DR-25 off the main harness where the connectors branch off. Not a crazy milspec harness or anything like that but its coming along and should look much nicer in the bay.
Finally got the harness all finished up, its nothing special but is a huge improvement over the stock harness I think. Has a much cleaner route through the engine bay and is completely heat resistant. Just have to add a few connectors and tape the seams in the harness up and its all ready to go. I am really happy with how it turned out and was a great leaning experience.

Hey man, love your build! Your attention to detail and commitment to doing it RIGHT is really impressive.
In your first post, you mentioned you moved over here from Probetalk; I'm thinking about doing the same from mx6.com. Thanks for showing me that it can be done!

That looks AWESOME. Love the coil-on-plug conversion in particular. I'm on my 2nd 2G MX-6 at the moment and would love to get rid of the KL's flaky distributor.
And yeah, I do all my question asking on the FB MX-6 group, but I hate FB for build/resto logs, hence my search for a forum (and one that's better than what mx6.com has become).

Hi @Allmotormx where did you get the ITB please or from which car? and... ur mazda looks amazing, do you have some videos of the sound?ITB's came in the other day and got them all cleaned up to get the linkages welded.
10mm spacers are needed to get the ports to match up on the heads.
My friend that's doing the welding for me also has the adapter plates getting cut out at her work, they are about 12mm thick aluminum.
Once I get the shape cut out for them I will start working on the ports. I'm thinking about making the bottom of the ITB's square to make port matching them a bit easier and also give a smoother transition into the heads. Still a work in progress though as I'm still not sure how to want to sync the ITB's together yet.
Also got my electric water pump in the other day and just did the wiring for it. I am just going to run it off a switch inside the car with no thermostat. Wired it to a constant 12v so that I can leave it pumping for a few minutes after a hot shut down.
