Someone said that it might be fore cruise control? I have a similar box on the back of my gauge cluster for my 91 HF and no one seems to know what it's for. The cluster does not have a shift light either.

In any event, does anyone have the pinout for it? I'd like to know what wire/pin is for what (ground - power - signal) so I can make some use out of it.

whats it to.

Not sure exactly what you're asking but...

I've got a 5 pin plug on my dash harness that goes into that blue housing in that box on the back of the instrument cluster. 91 HF.

sry ment what car it out of i see 91 HF

dacrxguy

on the service manual it says that if is for "HF" only so i am in the conclusion that it is the sift light i. i have a dx auto and man cluster and both of these have it. i disconnected it once but did not notice nothing funny.

if you look real close you can see that one wire goes to the circuit board to the mph and a ground coming off the tach. it then goes to the circuit board that is inside

yea I figured it was for the shift light but this cluster doesn't have on but does have the box. I think since it's a 91 the cluster doesn't have it and the 88-89 cluster's have them.


Can you identify the wires? I want to use it for ground and power, if applicable.

dacrxguy

well my auto 91 cluster had it but all i get when i look up the pins is d5-d1 no exact pin out is given but i will keep looking

dragvixen

according to my diagrams it is the shift light ur right

dragvixen

the pin on alldatapro.com says its pin d4

dacrxguy

that orange wire that hooks up to the bolt its location is a "speed pulser"

dacrxguy

here is the pinouts kind of hard to see

well I took a look at the wires on the plug and they are colored - GRN/yel - GRN - GRN/blk - RED - RED/blk

I'm guessing red = power and red/blk = ground

going to test it out with a voltmeter when the car is running again.

it's the factory shift up light for the crx hf...

I think that box has different uses depending on the cluster/car its from. On my CRX DX it's the speed sensor amplifier, on the LX/EX sedans it controls the cruise control indicator, and I guess judging from that service manual it control the HF's shift light. The red and red/blk are for the guage lights and are hooked up with the dash brightness control. If your car has green wires instead of yellow, you might find 12v on the GRN. I wouldn't use the red or red/blk for anything, you could burn out your dash light circuit.

Cool, I'll check out the grn wires then.

Looks like I MAY be able to make good use of it, thanks for the diagram.

Now does anyone know if the yel/red speed sensor wire goes to the ECU and if it is the same for electronic VSS?

according to that diagram, it mentions nothing about a shift light.
