I just did this last week, and I found it much easier to go ahead and remove the pod. One reason is that you will likely have to "reset" your pointer on the gauge, and to do so you have to remove the clear glass front ( and to remove that, you have to remove the gauges from the shroud ( all come out the back). Radio Shack has closed near my house, so I found a convenient Resistor by using the Rheostat from the headlight switch module. The two outer connectors on the rheostat can be adjusted using the thumbwheel and a digital Volt Meter. Set it at 55 ohms, and then connect it between ground and the connector at the engine. Turn on the ignition ( all wires plugged back in) and the gauge should read 260. If it does, your good to go. If it is off a little, might just leave it. If it is off a lot, then gently pry the needle off the gauge, and then gently re-seat the needle in the correct position and press back on. I used a tool normally used for popping the door panel "christmas trees" to pop it off, but I hear a fork will work just as well. It's a very small metal post you are pressing on, so be very careful.
