viper 5902 2008 f350 diesel

Yes the tach is connected and appears to be connected to the correct wire. I know all but one wire is connected on the H3 harness, and 3 are connected to the same wire. I will go out and check.

Ok here is what I got for the H3 harness... H3/1 Pink wire is connected to WHITE/ Orange in Ign Harness H3/2 RED / White is connected to WHITE/ Orange in Ign Harness H3/3 Orange    is connected to PURPLE / Green in Ign Harness H3/4 Violet    is connected to Blue/White   in Ign Harness H3/5 Green     is connected to Blue/White   in Ign Harness H3/6 Red       is connected to WHITE/ Orange in Ign Harness H3/7 Pink/White is connected to WHITE/ Orange in Ign Harness H3/8 Pink/Black has no connection H3/9 RED / Black is connected to Brown(maybe gray)/green in Ign Harness Thats those!

Major problems here....

Soldering is fun!

Kreg, Thanks man!    I leaving for a couple days for work so wont get a chance to mess around with it, but ill get to it as soon as im back and update. Thanks!

Keep us updated! Tell the guy to get lost. He has no idea what he is doing and surprised the truck even still runs.

Getting constant from an ignition wire, priceless...

Don't let the guy near your truck...

Dying to get working on this but still out of town. Lol, so 3 of those wires need constant 12v?!?   Unreal. He texted me today to let me know he had a new switch and should be good to go!   I havent replied yet....

Ok.    Got wires re done last night. Just went out and hooked up batteries and plugged everything back into the brain. Hit the remote start button and...................................... 30 secs later it starts!!!!!! I still have to connect brake kill wire, hood pin switch and probably some aux items (heated seats, defrost maybe?) I have one question right away though, after it started and was running I put key in ignition and turned to on/run position. Then I turned key off and removed and waited maybe a minute and didnt shut off. Would it be the turbo timer, or?   I hit the remote start button to shut down. I would like to thank everyone, esp Kreg357 for the quick respones and great help/info. I really appreciate it. I am mechanically inclined (do all my own work, install lift, exhaust, etc on my vehicles) I have always had a dislike for wires, id rather tear down an engine than deal with wires but this has made me feel alot more confident and comfortable working on electrical stuff! Thanks! Clayton

Good job!  We are here to help.  Now you have to come up with a good story for your friends "installer".

The Viper will continue in remote start mode until it sees the Brake pedal input wire go to (+), the Hood Pin

wire go to (-) or you press the remote start button again.  If the key is in the ignition and turned to ON whenyou step on the Brake Pedal ( called a "key take over" ) the Viper ends it's remote start control and the engine continues to run because the key is ON.

The Brake input is mandatory and the Hood Pin input is a necessary safety feature.   Just make sure you

solder everything, insulate with a quality electric tape ( Scotch Super 33+ ) and secure all the R/S wires neatly out of the way.  The 30 second "Wait to Start" delay sounds a bit long.  You can program the Viper for a fixed15 second delay, instead.

Soldering is fun!

Thanks! I tried getting into programming mode before but couldnt get it figured out or perhaps he messed something else up too.... I just happened to order a bitwriter last week so that should show up soon. Im going out to hook up brake wire, and finish tidying up the wires/brains.
