Thanks AF_Dali,
If I understand correctly here is the plan
(1) Start car
(2) Cut yellow wire (security light comes on)
(3) turn car off
(4) strip yellow wire ends and part of black wire.
(5) start car (security light is still on)
(6) meter between yellow (going to ignition switch) and black for resistance
(7) turn car off
(8) solder correct resistor between yellow (going into dash) and black
(9) start car (security light is off)
(10) post results to AF
Just want to get the steps correct so that I don't create a 4 door paperweight.
