wiring de-limiter

[Cambridge_pulsar]

I have a basic delimiter with no instructions, can some clever person confirm how it should be wired in. I have 4 wires red, blue, yellow, green. I know 2 are + and - do I just need to chop the speedo input wire and put it through the converter with the other 2 wires? Its a little black unit with the yellow wire coming out of one end and the others out the other end. If anyone recognises this could u identify the wires for me please... :?:

Thanx but i've already seen that and I need to know which wires i'm cutting, not just the colour as mine don't match the one he is using. help me pleeeeease.. :?:

suprised that dont just plug into the ECU like the Greddy one

i will have a look at thei instructions and see what wires do what

Cheers, I know it's really simple, think you just cut the speedo input wire, but don't wanna do anything till i'm sure what's what

Sounds like a CARTEK speedo converter/de-limiter.
Black box about an inch by half an inch, resin filled with two loops for a cable tie???
If so:
Red - ign live
Green - earth
Yellow - signal in (loom side of wire)
Blue - signal out (speedo side of wire)
