Gsxr750wr ECU?

[Tommichop]

So building a chop from not alot (see Slingshot chopper in the project section) but I'm struggling with wiring my ECU as although I have the correct wiring diagram for the ECU, I'm still not sure which colour wire goes where when entering the ECU (fitting into the socket) has anyone got a picture of a 4 and 6 pin ECU wired up, or just the wiring loom plugs. 

1994 gsxr 750 wr 

 

Anything appreciated, cheers Tommy

This is a RF900 loom but will be the same. Ignore the pink wire if you have it you can take it out altogether

It's black red on the bottom right of the 6 pin plug, but only needed if you think a rev counter is of any use

That's perfect, I appreciate that. Sorry, I didn't see it earlier. Thanks again

Well I'm all wired up, as above, but lacking the vital spark on either coil. Tested coils and pulse, all good. I'm thinking ECU is fried, unless anyone else has any ideas???

If that is the case,would you guys recommend reconditioning or a new aftermarket type, any thoughts appreciated, well thoughts on the subject that is

Hmm thats weird.

So you've got switched +12 at the orange/white wire ? And ground is properly connected ? 

- Have you sorted out the kill switch system ? 

- Have you bypassed the sidestand/neutral security cut off system ?

Both those will prevent spark at the coils.

Also, what exactly is this "loom" we can see in your photos ?

Could be the ECU, some are known to vibrate to bits but at your state of a project difficult to assess that.
