[Shotimes] Re: How to test PCM

[Kevin & Cheryl Airth]

Louis:
 The breakout box installs between the main wire harness plug and the PCM.
It only allows you to connect to any wire/wires/circuit while they are in
use. You must still use a meter to make any readings. It's just so much
easier than probing the individual wires! Plus everything is numbered.
 Please post any reasonable priced ones you see! I would love to get one to
play around with!

are a few used ones for sale on ebay that aren't unreasonably priced.
