Little update.
I got home from work today to be greeted by a little box, containing my new rev counter
Its only the base model one, I did look at getting the st700 but the only thing it does that I dont already have with my spa's and secs is speed and I didnt want to get rid of my standard rev counter and speedo, as I have nothing else to put in there so I went for the pikey option and im just going to replace the standard rev counter

. Next thing is to collect my 92 spec dash and then I can rip it all out, replace the main feeds from the battery to the fuse box and fit the rev counter.
