I know this is a pretty old thread, but I need your help! Both the 200K and 300K resistors come in different wattages. So, can someone help me out here and tell me what wattage the resistors should be? I really appreciate any and all info you could supply.

I just stepped into this thread, and going through everything for some future reference. I really need to read everything to get up to speed.
if you don't have the answer by now, here's my 2-cents. not sure what the voltage is across the two pins on the integrated circuit, but using both 200K and 300K resistance values, and 12 VDC (just a guess, but most likely 5VDC), using simple ohm's law, the power (in watts) calculates either .48 or .72 milliwatts (for the 200K and 300K values). I'd say an 1/8W resistor would be more than enough.

hope this helps -
Thanks Joe: It's good when you get two responses that match! On another thread, a long time member came up with the same result. Now I feel confident that I will get the right parts....then comes the real fun.
I know this is an older thread, but having said that.

As soon as I find the dash connector I need for my dash change project, I will be removing the cluster from my 93, and can measure the resister.
