Thank you for all your help so far... I am trying to search as much as I can before asking questions.
I recently rewired the boat we acquired and put all new sierra marine gauges. The trim gauge has the purple 12v line coming off of the tachometer.
At the moment, the purple line from my tach is daisy chained to my voltmeter which then daisy chains to my trim gauge. Does the voltmeter interrupt the current needed? Purple wire to 12v, Brown/White to Sender, Black to Ground, Blue to lights... it doesn't seem to work at the moment.
Sierras instructions gives two wiring scenarios for mercury: a wire that piggy backs from ground to sending unit post OR as mentioned above.
If my wiring harness came equipped with the brown/white wire, is it safe to assume I have a trim sending unit on my 1989 Mercury 115 4 cyl? If so... where is it? Can't find part numbers for it which leads me to believe it doesnt have one...
Please help if you can, thanks in advance!
