Actron CP7677 Great!
I've used this the past 2 days installing my Viper 3002 Alarm. It's going to help me a lot with this 81 Jeep CJ7 where the past few owners have made a rats nest under the dash and to rewire a lot of things on my vehilce. I've used the voltage, amps, tested diodes, relays and a few other things. Great Buy!
