I have finished udating my instrument panel and thought I would pass on some of the results.
The harness was fine and even the plugs were in perfect shape. The Alt output is not through the panel and I have now installed a pre-heat solonoid so there is only very low current running through the harness and I saw no reason to eliminate the plugs or replace the wiring harness.
I purchased a dual tone alarm fro Cat. Dir, ($24.00) and installed it on the panel. I removed the old water temp guage and replaced it with a
FW Murphy water temp switch guage (EGS21T-250-12). This guage has an adjustable switch which will activate the alarm when the pre-set limit is reached. I attached it to one lead of the alarm. This guage will not work with the stock sender; I used an FW Murphy sender with a 1/4 NPT adapter
(EST-250/300 1/4). This works fine in the stock thermostat housing and is connected to the existing wire.
I conected the oil pressure wire to the other lead on the alarm.
So I now have oil pressure alarm (it had not been working) and coolant temp alarm. Happy with that.
I also installed a raw water flow alarm. It did require running one wire from the enging spaces to the panel. On the panel I mounted it's dedicated alarm and warning light. It works nicely. Happy with that.
If you want to know , I have had a fan belt failure and a sea water strainer clog, both of which sent the temps soaring. I noticed both before it was too late but felt that the lack of "bells and whistles" needed to be fixed.
I'm sure that for the most part newer boats are well protected in their stock condition but my '92 needed the upgrade.
Everything else on the panel is working fine, so I saw no reason to change out anything else except for a few sketchy looking connectors.

Neal,i did a similar upgrade to my 1990 panel after a bad plugged sea strainer scare.(just caught in time)..I purchased a water temp sensor from CD and screwed it into the bleeder valve of the thermostat housing(tossed the bleed valve)then ran the wire to the 2 tone alarm along with the wire from the oil pressure sensor...
I would also like to install a flow alarm on the sea strainer(or wherever appropriate) Can you tell me details of this install?Product?location? thanks for posting

Greg, I used an "Aqualarm Model # 13209/306-LF. At Defender Marine it is Part # 551458 and their price is $62.99. I mounted the unit in a bracket which I made, on the starboard side of the engine with my bracket screwed to the fixed wooden side of the engine housing. Some feel that as this part is made of plastic that it poses a threat of failure and if one were in a freezing climate that may be true. The unit seems very robust and I would expect other things to fail long befor it ever leaked. It has one inch female threads on both ends which will need to be reduced to accomodate the existing hose between the strainer and the raw water pump. I did this with a PVC reducer bushing and bronze hose fittings. I'm sure that there are lots of other ways to do it and I feel pretty secure that it is as secure as other parts of the system. It only took a few minutes to adjust it to the flow rate of my engine at idle and seems to work well through several start and shut down cycles. Only time will tell about how it holds up.
I hope this helps.
