Johnniee,

You have to bear in mind there was a fair bit of time invested in figuring all this out. That took me a few weeks.

With all the parts ready to go, it took an hour to do the whole disassemble-reassemble and then 15 minutes to calibrate the gps. Pretty easy once you know how to do it!

Obviously this doesn't include time spent developing your wiring harness. What stage are you at in the conversion?
