Well the install was much more strait forward than I firstly anticipated. Only real boot fab was taking the fitting off the toyota speedo cable and adapting it to the speed sensor provided. The problem being the kit comes with a mechanical speed sensor or transducer. Everything went in very well, first time around took about 6 hrs, should be able to shave some time off the next one. Been thinking about offering a 24 volt version, kinda nice for those long trips. 12 volt kit cost around 700.00.
