Discussion and questions related to the course EFI Wiring Fundamentals
I'm trying to build a new section of harness for a Mazda 3 MPS and I'm having difficulty sourcing the OEM connectors. I'm trying to avoid going directly to a Mazda dealer as they are heaps expensive here in Australia.
Any help in finding these connectors would be greatly appreciated.
I did check bmotorsport but I could only find what looks like connector 2. I couldn't find the others. Some looked similar but not sure if they exactly fit
Often you just have to start with an OEM harness from a salvage yard, especially for those large multi-pin connectors like your first & last ones.
When I build harnesses for the Mazda MZR (2L NA version), I use the following parts:
OEM Coil connector : Ballenger Motorsport CONN-75775
Cam Sensor connector : Ford pigtail WPT-990
VVT Solenoid connector : Ford pigtail WPT-349
That is the only OEM sensors/connectors I use, everything else is different on my engines (temp/pressure sensors, crank trigger, etc).
Thanks David. I might have to reach out to mazda or get a wrecked harness for the other bits.
