I'm sure this is been talked about 100 times, sorry. <br /><br />I have a 98 Monarch with an 86 merc 4cyl 75 red striper. It came with a 40 forse which i quickly swapped out without much problems at all. Anyways, I currently have a speedo and a fuel gauge and thats it. I need a tack so I can watch the RPMs on the motor. I plan to buy a standard tellex, or whatever their name is, and install that. I bought the merc manual (90-86134--4) but am still confused. Will this be easy, or will I have to run more wired than what is in the harness already. When I look under the console, it appears all the wires have a home and I see no extras for tach and other gauges...can anybody guide me along..thanks
