Knock Gauge

[Paul Clark]

I have both the gauge and the audible.
The instructions say to basically wire both of them up the same way.
You should splice and solder into the same computer wire.
Correct?
What is the best way to do that, and is there some kind of connector that will allow you to avoid cutting off the insulation to the computer wire?
Thanks

Yup, they both go to the same yellow wire with black stripe.

Power and ground also but that can be easily tapped into the fuse box and a metal screw without affecting factory wiring.

I soldered mine to insure a good connection.

Those crimp on splices are iffy for something as important as knock detecting devices.

I usually just displace the insulation without cutting the strands at all, wrap the new copper wire around it, or two wires, and then solder for a good flow and do a pull test.

To repair the area after desoldering I would probably just go with some yellow 3M electrical tape. Don't ever plan on having to do that however.

If you really have your heart set about not cutting then use the proper gauge crimp device with ONE wire in it and solder the two new wires to a short length of wire out of the crimp on device.

Don't ever try to jam two wires in one.

Those crimp thingies also cut through the insulation and can mangle a wire if not done right.

Just my .02.

Thanks.
Where did you put the audible thingy? Seems like the closer you could get it to your ears the better.
Also, do you need to run 2 seperate wires, or could you splice them together someplace a few feet away from the computer and then just run one wire to the computer?

Both of mine are hanging by the ECM, plenty loud enough even with a helmet on.

One has the plastic ECM cover one doesn't and I can still hear both of them. The one with the cover is tucked up out of the cover on top of it under the dash area.

You can run one wire to the computer and splice the two into it especially if you are going to use one of those crimp connectors.
