Volvo 290 trim sender help

[f_inscreenname]

Need to know how to wire up a trim sender and to make sure I get the right gauge.
The sender has 3 wires coming off of it. One with a red strip, one with a black and one with a green stripe. Where do these wires go to? Also I see there is a couple different Volvo trim gauges. Some that say they will work with MERCURY/VOLVO/YAMAHA and others that say they are a TRIM GAUGE with MASTER BRAIN. What type do I need?

I would bet that gauge is used for the SX type drives, not the older 290 style. I've never seen an analog meter on an older DP without the black box and associated wiring.
Here is some info I have on the black box, and testing the sender which will give you the ohms rating you have to work with.

I take it the black box is up under the dash or something because i got the whole thing from bellhousing to prop but saw no black box. And I bet that box is expensive.

That cheap sender is $150, the black box close to 300 about 6 ot 7 years ago if I remember correctly. Those black boxes also had a high failure rate.
Then you need all the special ended wiring harnesses, relays etc. to make it all work. Probably really what you want to spend. If the sender is ok, You might try working a regular trim tilt gauge with it to see if you can make it work.

That sounds a bit extreme ($$$$) to just fill a hole that hasn't been cut yet in a dashboard.
How would you go about hooking up a normal gauge. From the one I found the gage looks like it has 3 terminals. Is one of the three wires from the sender a "sender wire" and the other two for power and ground?

Never tried, not even sure that sender can even handle a gauge. They were only used to send info to electronic. Either the black box or a digital gauge with built in electronics. When I changed my boat from a 280 to the 290DP with trim, I just used a switch, no gauge. Verified the drive was down before starting, and just trimmed by the seat of my pants. No gauge needed.

That's what I will do then. Thanks for the help.
