Smile What a mess, and by mess I mean fun

Finally finished my EBC and KnocksenseMS wiring.

I'm waiting to hear from innovative about the status of my LC-1, and want to wait for it to come back before I bolt it all back up (I'm rewiring it)

but anyways here's how mine looks right now.

mess of wires:




knocksense unit:




LED (lights with knock events):




Boost solenoid:

wow, you really worked hard to use the stock harness. I just made my own for the engine harness and kept the instrument and power harness intact. I like the knocksense LED

it looks worse than it is, it's a typical boomslang, however it's all mashed together in one spot to fit under the protective cover....

can you go a little bit more in depth about this knocksense. What sensor did you use and where did you place it?

My GTX motor came with a knock sensor and a control box (probably just a filter) and I'm curious if I can use those or if I have to use something that has an existing tested calibration.

EDIT: Nevermind, I found the website, but I do still like to know where you connected the sensor.

Hey man I have the same kind of mess. Especially with that switch box of mine. I have the connectors and all of that to build a patch harness which I will be doing as well so I don't have to tap into the stock one anymore. I hate tearing up the stock harness.

I have a couple of empty bolt holes on my motor so I guess I will just screw it on to one of those.

What is that gray stuff? JB weld?

im not, scred in stud, then torque a nut down on the flange....then the sensor, then the second nut, and one lock nut for good measure. I suspect the JB Weld might filter out some noise/knock and get bad readings...

yeah I have one here in front of me, and it literally is just a bolt with an allen head and a big *** nut. The bosch sensor is caputured between the big *** nut and the allen head.

I gotta get on my wiring...that **** scares the hell out of me though :(

However, I did get my clutch done without knowing what I was doing, and I've done a LOT of research into megasquirt...so maybe this wont be as bad as I think.

And who the chuff apart from me is going to see it? (granted a few people as I've photo'd and and posted it on a forum but you get my point)

Anyway I've not JBwelded it to the block, I've used JBweld to attach a bolt onto the block and the knock sensor is sitting on that bolts thread and torqued down with a nut and washer at both ends.

I don't see how the JBweld will filter anything out considering how hard it becomes once it's cured.

Some people need to get in the DIY spirit considering they're all using a DIY ECU
