I did the 10 k mod on my 96 PS today & next want to do the IDM mod. What is the resistor that I will need & does radio shack carry them? Thanks fellas.

I did that mod, also, with radio shack resistors. OHM them out to make sure they are exactly what you want. The % on the pack is the accuracy. You may need to put one or more in line.

no. either 75 or 78k. look on your IDM and see waht volt it is, it on the sticker. i dont have a pic, but its either 100 110 or 120v. i think its the second set of numbers. look under the hood on the drivers side fender.

the 100 and 110v IDMs need (1) 75k resistor. 120v needs (1) 78k resistor. i had to stack because the resistors werent exact. thats what the% on the pack means.

Here's my IDM write-up with pics. Hope if helps.

Also, make sure you take the 10k off before you put your chip in. The chip controls that for you so you don't need the 10k. I have a PHP chip and I love it!
