Pre-swap wiring questions - BP4W into 92 NA6
Hello all,
I've finally finished building the motor and am going to attempt to install it this weekend. I just wanted seek clarification or a set of second eyes when it comes to wiring...just to be sure.
I am going to be upgrading to an MS3 unit and will be retaining the BP4W sensors. To merge these sensors into the NA6 harness, I need to ensure that they are connected correctly.

For the Crank/Cam signal
Stock 1.6L CAS:
black w/ light green stripe = Ground
white w/ red stripe = +12V
white = crank signal
yellow w/ blue stripe = cam signal
on the BP4W Crank Sensor:
White w/red stripe = +12v
Black w/blue stripe = ground
Grey w/ Red = Crank signal
on BP4W Cam Sensor:
White w/red stripe = +12v
Black w/blue stripe = ground
Grey w/ Blue = Cam signal
essentially, I can split the power and ground from the stock CAS and wire it into the respective white/red and black wires on the BP4W sensors, then just hook up
[NA6:white to BP4W:grey/red] and
[NA6: yellow/blue to BP4W: grey/blue]

just connect the wires as polarity doesn't matter?

TPS
NA6 Red = 5v reference
NA6 light green/white = TPS signal
NA6 black/green = Ground
BP4W Light Grn/Red = 5v reference
BP4W Green/Black = TPS signal
BP4W Black/Red = Ground

Electronic boost control solenoid
Is there a switched 12v source I could use for the EBC? I am pretty sure I can hijack one of the wires back to the ecu and relocate it to be used for Megasquirts Boost Control function.
I think that's it for the wiring. As I recall the fan switch that was at the front of the block is now obsolete since megasquirt controls the output.
ANY insight or correction to the above would be greatly appreciated

Can someone take a picture of their blow to so I can see what the colors should be for the plug?
The pigtail I have does not match the factory colors at all.
My tips pigtail has:
Brown with yellow stripe
Brown
Pink with black stripe

Also my crank sensor pig tail does not match, but am I safe in assuming black is ground, red is power and blue is the signal wire to be connected to the CKP wire from the 1.6L CAS?
