Just got my $75 tachometer sender unit from SI, Instructions say -"do not wire
this unit wrong under penalty of...and it will burn up---and its your fault!
I also warns against wiring as the original car install.. Gee Whiz! Any one got one to work sucessfully.? What to avoid?
It's the Non-R1, rectangular box shaped one.

I put mine in about 3 years ago, no problem. It's worked fine, just follow the instructions. Some of the original equipment tachs were wired backwards from what the new one is. If you were to connect it in that fashion, I guess it would fry.

Thanks GT TIM, I'll proceed with caution but nice to know you were successful.
