here's some more info. it totals around $350 with the
speedo being $260 and the SEN-1011 converter being $30 plus shipping and the adapter for the "dash",
carlini's paint saver plus, around $25. the speedo is 2 1/16 inches in diameter which is smaller than our tach/clock hole so an adapter must be fitted. having looked at many options i went with the 'paint saver'. after removing the rubber gasket it was a near perfect fit on the dash but needed to be opened up to fit the speedo. the husband of the owner of the shop i bought the 'paint saver' from works in a machine shop and made the hole in the center of the 'paint saver' a hair over 2 1/6 inches by mounting it in a lathe and cutting the center circle out. for free no less!! next i had to figure out how to get the dissimilar sized speedo cable end and the "converter" for the speedo to match up. the converter has a 5/8 threaded coupling for a speedo cable and ours is 12mm. after much thought and checking and rechecking i decided that if it would work at all it would work with just the inner cable (the part that spins) inserted into the converter and it wouldn't matter how the outsides of the speedo cable and the converter were held together so long as it was a solid union. i decided to use a
1/2 inch metal conduit coupler which test rode satisfactorily. the newly joined converter and speedo cable (barely) go into the headlight bucket which is also where i picked up switched pos and neg power off of an unused connector (which btw i have no idea what it was for, i'll post pics). i just followed the included simple directions for wiring and positioned the included waterproof push button momentary switch which is used for calibration and display options including resetting the trip odo. making the wider "u" bracket for holding the speedo and adapter to the dash took some fine tuning as all i had was 1 inch flat zinc coated metal, which is too wide and had to be cut down. i may do it again with a piece of 1/2 inch and i may move my electric pickup to the clock harness under the dash (which i found after looking for everywhere
except under the dash! doh!). a combination of a 6-wire plug in the back of the speedo, solder/heat shrink and dielectric grease filled crimp on quick connects makes the dash, with the speedo installed, completely removable. and i know, without pics this is a little pointless so i'll try to get some tonite. i haven't had the opportunity to calibrate it yet but it acts like its supposed to, speed increases, holds and decreases as expected. it was cool doing 195 mph sunday and 27 miles in around 12. you calibrate it either by following a vehicle at a known speed or by running a measured mile. i do not expect any calibration issues but you may want to wait until i can get mine done before jumping into this as it's the only unknown left. it's snowing like crazy right now but maybe by this weekend it'll be clear enough to give it a shot at calibration.
