Issue with tilt and trim

I need a little advice I have a 1987 thundercraft citation I/O with a 3.0l merc and a merc alpha 1 outdrive I have now completely rebuilt motor and outdrive but am having an issue with the tilt trim switches (they werent connected when i purchased boat) and cannot find any diagrams on the net to assist i'm running a two switch setup the trim is working I have the trim wires attached to the hydraulic pump my problem is the tilt has no activity when button is depressed. I have a total of four wires (2 pairs taped seperatly I'm assuming one pair for each switch) coming through the gimble housing the blue and purple wires are connected for the trim the pair that has just a red and black is what i'm trying to connect the other switch but have no clue whether they need to be attached to the hydraulic pump or just to power itself. any advice would help even a link to a schematic




Thanks

this is the only diagram I have ..if you have two switched then its just another set in paralled with the first ...

Re: Issue with tilt and trim

The above diagrams are for relays, not solenoids used by Mercruiser.
Below is a pdf file for troubleshooting your trim/tilts system with the proper wiring diagrams on the last page.

Don I noticed in the diagram though it's only showing one switch, on the back of my alpha one I have a switch on both sides of the outdrive is that a whole nother subject or in some way is it tied into what i'm' trying to accomplish I've no experience with the dual switch setup this is why i ask
