Retry Trim wiring help

[angel_guardian]

OK from scratch: I have a 150 Merc Black Max (82-84) SN 6009047 that came with the arm on the transom with two hydraulic lines coming up over the top of transom (SN 79610A1); I recently bought a trim pump (SN 88183A11) and the wiring colors do not match up. From the trim pump I have a Positive and negative cable (get those out of way); in the wire sleeve I have a thin blue, thick green, thin purple and thick red; now from the motor wire harness I have a thin blue, thin green, thin tan, and thin blue; Now what I have accomplished so far is that when I connect the blue and blue I get clicking in the up relay and connecting green to green I get clicks on the down relay. Question 1 why is it clicking and not trimming up or down; Question two what are the extra wires? (pump: thin purple, thick red and motor: thin tan and thin brown). Thanks for taking the time to read this all I'm trying to get all details out of the way!

Try going to http://1manual.com/Mercury manuals You will need to download the manual as it takes awhile. It has wireing diagrams for your setup that you can follow to make your trim work. From what I can tell your motor is for selinods and the trim motor is for a relay setup. You should be able to switch to one or the other without to much hassel.
Your motor harness the tan wire is for a water temp gauge, the purple is a spar 12v+ an the brown is I think for the warning system. Sorry it's late here and I do not have my Merc manual right here now. Try the download and let us know if you get it.

Sorry but you will not find your manual at that site. Yours is an early '80s engine:

From here:

It is a model 1150620.

OEM Service Manual for s/ns S/N 5464486 thru 0C100860: 90-976583

Here is the condensed version of the Clymer service manual but it will not have the trim wiring. Let the page load for several seconds and then download soonest to your computer as the link is short lived.
