Hi guy's just finished fitting my gear indicator so thought i'd share it with you.
I went for the healtech, model GPDS-T01.
Its quite easy on the sprint st 1050 main plug of the unit just plugs straight in to the diagnostic connector in the glove box.
Tricky part is connecting the +12v power lead.
The instructions say to fit it to a +12v power supply which is switched on only when the engine stop switch is in the run position.
They suggest...... ' you will find such a wire in the extension plug for the optional alarm, hot wire of the licence plate light or at the fuse box '.
I couldn't find the alarm plug, took the tank off to have a look, i believe it is under there somewhere, but drew a blank.
I decided to think about what is needed and apply a bit of logic to tackle it my own way.
+12v power supply that needs to be switched on and off with the ignition but also be turned off when you hit the kill switch.
With the ignition turned on but the engine not running i noticed that if you hit the kill switch the instruments all go out but the lights stay on.
So i decided that i would have a look at the wires from the kill switch and traced them back to a block connector.
I attached a length of black wire that i had left over from another job just to make things a bit easier.
Here's a few pic's
Disconnect plug and pull it out from above for easier access.
Red wire shown in photo is the one i spliced into.
Soldered my extra wire and joined them both back together then heat shrunk them.
Taped the loom back up nice and tidy.
Soldered and heat shrunk my extra wire together with the +12v from the healtech.
I mounted it here in the end, thought about the clock surrond, but didn't fancy it.
Happy fettling guy's.......
