I'm currently doing a AUTO-5speed swap which I purchased a brand new 5speed harness from Malloy's Mazda. The question I have is what connects to the BLUE (10bit) and WHITE(14bit) connectors that is on the 5 speed harness? The auto harness's BLUE and WHITE connectors are larger and will not fasten to the 5 speed BLUE and WHITE connectors!?

The 5 speed harness has the following connectors:

-BLACK (8bit)=connects to what?
-BLUE (10bit)=connects to what?
-YELLOW (16bit)=connects to ECU
-YELLOW (26bit)=connects to ECU
-BLACK (wire)=ground
-BLACK CLIP=original auto harness was not connected

The other harness separate from the 5 speed harness are:

-YELLOW=ECU
-YELLOW=ECU
-BLACK=Control Unit?

If anyone can provide assistance, I'd really appreciate it!

I don't mean to hijack your post but I'm very confuse about the in-dash wire harness. I have a five speed engine wire harness already have all the parts. But I ran into a problem with my in-dash harness it would not fit the manual ecu.

The main question I have are:
1)Do I need manual in-dash wire harness.
2)If I do get the manual in-dash wire harness will it works with my auto instrument cluster(existing instrument cluster)?

Thanks for the help inadvance.

 

You do not need an in-dash manual harness. If you search and also read what Mahjik has posted all the answers will be revealed unto you.
