ok, I just noticed you have a 98 but something like this SHOULDNT be that different.
FAQ this mods...
If you look in a Haynes manual, look for what color the "illumination" wire is. In the first gen's, if I remember correctly it's red w/yellow. There should be one of these color wires in almost every plug into the back of your guage pod. The illumination circuit only receives 12v power when you flip you parking lights/headlights on, hence powering the transformer on the indiglos. Get a box or a few 18-22 guage (red)
wiretaps from lowes or home depot (even radio shack)
The way the wiretap works is it has a slit on one side that you slip over the existing wire, which would be your illumination (red/yellow) wire. then to the side there is another hole where you can slip another wire in. You'll notice there will be a metal clip that looks like an 'M' that when compressed (use channel locks...they work the best to squeeze it down into the plastic) will "tap" both wires and give the new wire connectivity through the existing one. this will be your 12v power supply to the transformer on the indiglos and will only receive power (show indiglo) when you turn your lights on.
For the ground, look on the back of the guage pod and you should be able to find at least two screws with
GND next to it. This is a grounding point on the guage pod. get a small ring connector and crimp onto the end of your ground wire coming from the indiglo transformer. then remove the screw, slip it through the ring connector and screw it back in. make sure you dont touch any of the gold tracks on the back of the guage pod. This could cause other things to short or..."ground out."
Thats it...get some zip ties and tie all the cables together and put your guage pod back in.
Oh...and I almost forgot...mine came with a dimmer knob/switch for the indiglos attached to the transformer. To get the guage pod out, I had to pull the woodgrain strip out anyway so I drilled a hole big enough to slip the stem through the woodgrain strip, removed the little nut on the knob, slipped the stem through the hole, screwed the nut back on tight and slid the knob back on. easy.
