What kind of ECU is it? Just the standard one that came from the DC2R? Or is it an aftermarket one (hondata etc) with a rev limiter?

stock p73 dc2 type r computer no hondata i got it from jdm yard no wiring diagram nothing

I'm not familiar with the P73 ecu's, but it looks to me like a plug n play harness for an aftermarket piggyback/rev limiter setup? Will the car start without these wires plugged in?

Red: Power source
Black: Ground
White: Handbrake/clutch switch with ground
Yellow and Green: Taps into the ICM wire?

someone correct me on this..
but yeah, try and start the car without plugging them in to anything.

Ask ECU-MAN

[ECU-MAN]

do not assume red and black are power and ground. you will quite quickly blow up your ECU

they will be for

PO2H
KS
PSPW
VTP
VTS

as for what colour wire is for what, you either need to contact the reseller as mentioned above or follow the wires back to the OBDIIa connector and identify the pin it connects to then Identify its function
