    Nope: when you replace the circuit board, you have to loosen the nuts holding the various gauges. The posts can easily contact the metal housing when reinstalling and tightening the nuts, shorting out the CVR output and the gauges will not work. This is a chronic problem for 69/70 dash clusters. The cheapest solution is to remove the circuit card and place black electrical tape over the rectangular cutout sides so that the posts won't contact the metal housing. Re-install the cardboard insulation pad, the circuit card, and tighten the nuts. As a check, you can measure the resistance between each post and the housing metal. If you see 1 to 14 ohms, one of the gauges is shorting out, causing the others to short out too. The ammeter, if shorted, will cause a massive short and because the lines are not fused, can cause a fire. Bad design by Ford.

    your sensor of the fan activity should be located at the exit of the radiator/entrance to the engine (lower hose). basically, if the radiator (without fans) is able to adequately cool the fluid before it enters the engine, then there is no point in turning on the fans or have them turned up. locating that sensor in the intake manifold will basically have you running the fans more necessary. which of course won't hurt beyond consuming a little more energy/power at certain times.

    69 mach1 Wheel and tire size

    Just adding my two cents to this thread... I found that modern tire design and brands, such Nitto do not make many, if any performance tires below 17 inch diameter. On my 70 Mach 1 M-code, I went with 17 US Mags Bandit rims and Nitto NT555 G2s. I have factory height big block constant 640 lbs rated coil springs up front with Global West suspension and a 1" Shelby drop (upper Arm Control). Global West Plus 3 upper arms have 3 degrees of positive caster built into them. This will eliminate the need to pull the lower arm so far forward in order to get the optimal alignment. In the rear I have stock height 138 lbs rated/Competition Handling Eaton rear springs and an aftermarket 1" rear sway bar. The US Mags Bandit front 17x 8 with a 1 Offset and 4.54 backspace with Nitto NT555 G2 245 x 45 tires. The rear US Mags Bandit front 17x 9 with a 8 Offset and 5.31 backspace with a big Nitto NT555 G2 275 x 50 tires. I prefer the look of a larger width and height rear tire. I did have to roll my rear fender lips. I also lightly rolled the front fender lips too, but I don't think I needed to.

    Front 17X8 245/45 0° offset Rear 17X9.5 275/40 0° offset Stock suspension with no rubbing anywhere. Edit: I did roll the fenders. Got it back on the road last Friday after a 9 year resto.

    You should be seeing 1 ohm or less between chassis ground and the battery ground. Anything more than that, and you'll begin to have problems. Ask me how I know... OK...I'll tell you. My wife is trying to put me 6 feet underground so I can test continuity to ground...I'm trying to convince her that a copper or steel red/pipe stuck in the ground is just as good but she's not having any of that...
