Harrop 2300 supercharger to Optimiser 6500

Righto, scotch locks worked, got the connection, no fault, and the power to the dash controller is functioning, there was a plug end missing from the dash mounted controller so it wasnt getting power, no sign of the missing plug, just 4 bare wires - WTF. Anyway, I stripped and soldered the cables together and looks like I am past Diagnostic Step 1. Yee Haaa. Next is Step 2, trying to squeeze some time in but work is getting in the way. I am sure glad, as I am sure a few people on this site would agree that I never selected auto electrical as a career - I consistently manage to make a mince of this stuff, but money and time does compensate it guess!! Stay tuned for the next step.

Fired up the cruise control again yesterday to move to step 2 and no go - actuator not responding. I did another troubleshooting hunt on the internet and found another start up and trouble shooting procedure for the same model , from the same manufacturer with different comments and instructions. So I did a couple of tweaks today and waiting to try it later, but seems there are two models of this CC avail and I didn't know this. There is the model I have with the magnets on the tailshaft and then a model that takes a feed off the speedo output in the dash - to some degree I am happy with the tailshaft set up as long as it can handle corrugations - but first just need it to actually test cycle - bloody frustrating.

I have had similar units on other vehicles. You should have no issues with the magnets on the tailshaft as long as you use double sided tape and the wires nice and firm and crossed over between the magnets. I have also used magnets recovered from 'phone receivers (common items used by a previous employer) and could probably locate some if you need them.
Mounting the sensor coil and magnets needs to be such that there is no risk of them hitting each other but remain fairly close together as thimgs flex and shake.
