HKS Camp question

I've got a used HKS Camp computer, but no manual. I was wondering if anyone out there could let me know which wires on the 'computer' wiring harness should be spliced to. The harness I have seems to be missing the end harness, the colored wires end in a white plastic socket that looks like it connects to the other half of a socket with maybe a fuse in the middle. What exactly am I missing? Could I just cut the sockets off and splice directly when I find out what wires go where?

Can furnish a picture if that was confusing... =)

Thanks in advance!

Note:
Just looked at the cabling again, if it follows spec then:
Red = 12v ignition
Yellow = 12v constant
Black = ground

I need information on the following leads:
blue = ?
green = ?
brown = ?

The Green and Brown wires have a plastic connector on them, do they go to the optional junction box?

That would leave the one Blue wire to splice to the ECU, which wire on the ECU would that go to?

Any help is greatly appreciated. This CAMP is staring at me and begging to be installed. :)

Nervous,
That would be awesome, thanks for the help.
I was given some information from someone, but if you can verify this that would be great.

Green Wire = injector pulse signal
Blue Wire = Vehicle Speed Sensor
Brown = RPM Signal

These wires need to be 5v digital signals, T-spliced in.

If you know which ECU wires these splice to, that would be great too. I am going to look it up now.

Thanks,
Rich

Ok, I've looked up the ECU wires I need to splice the CAMP to, and here's what I've got:

GREEN = injector pulse signal
E9-15 [#60] No 6 injector
E9-16 [#50] No 5 injector
E9-17 [#40] No 4 injector
E9-18 [#30] No 3 injector
E9-19 [#20] No 2 injector
E9-20 [#10] No 1 injector

BLUE = Vehicle Speed Sensor
E10-2 [SP1] No 1 vehicle speed sensor
E9-23 [SP2 +] No 2 vehicle speed sensor
E9-3 [SP2 -] No 2 vehicle speed sensor

BROWN = RPM signal
E10-16 [TACO] Tachometer

Questions:
Does it matter which Injector wire I splice green to? I would think not, but is there a preferred one?

Should I be using SP1 speed sensor for blue? I see SP2 is split to a negative and positive.

BROWN is straightforward... =)

If any of you all with a CAMP installed can remember what you spliced to, would help a lot. thanks again.

Update:
I went ahead and installed the CAMP today. Something seems to be incorrect, but I could be wrong. Here's what I finally ended up doing:

Blue to E10-2 [SP1] No 1 vehicle speed sensor
Green to E9-20 [#10] No 1 injector
Brown to E10-16 [TACO] Tachometer

Then I took a cruise around town. Here's what I found:

RPMs on the CAMP seems to be higher than the car's tach.
Sometimes as high as 1000 RPM over the car's tach, but at idle the car shows around 900RPM and the camp is around 1000RPM. As RPM increases, the greater the disparity between car and CAMP. Is this correct behavior?

SPEED on the CAMP seems to be way off. I realize that the CAMP shows km/h and not mph, but comparing the car's km/h to the CAMP shows a disparity of +20 or more.

Injector percentage looks fine

Could I have tapped into the wrong ECU vehicle speed sensor? There's 3 listed in the reference guide. I might have possibly done the same with the RPMs, but I didnt see anything else that would give me an RPM readout on the ECU guide.

Please, someone with a CAMP installed help me out.

Make sure your RPMs are setup for a 6 cylinder. If not it will be thinking that you have a 4 cylinder and the rpm are about 1.5 times higher. I don't know if this make a difference or not but you could try.

Did you ever get this resolved? I am having the same RPM problem with my Defi VSD Concept. It reads over 1000 RPM higher than actual. I tapped off pin 58 on the ECU.

The speed sensor wire I used was right off the harness that goes to the speedo gauge. It's a blue wire with a red stripe. The speed is dead on so maybe that will work with your CAMP as well.
