Turbodiesel
Thank you for the reply so quickly. I looked under the seat and found the location you indicated however the REARALERT (ebay $14.95 + 4.00 shipping) was so small I decided to install it in the chrome V behind the license plate. It fit perfectly and I also took your advice and used male and female bullet connectors so it can be removed with basic tools. Thank you again!
BTW, My next purchase will be the SOS Priority Lite ( http://www.compacc.com/p.cfm/c/1405002/p/524 ) this unit looks bigger and will have to go under the seat. Good reviews and my rear amber turn lights become running AND stop. (Yes, I checked and it is legal in WA.)
