1988 Silverado C1500 viper remote starter

Wiring problems:

1988-1998 Cheverolet Silverado C1500. viper remote starter install
2 Door. Power windows. No security key. 1998. Gasoline.
Attempting to install a Viper 2 way remote. Model: 4305v1 (info sheet attached)


Thank you to everyone over the years that answered questions on this forum! I found wiring info and lots of help before needing to post. This was my first install attempt. About all I have so far is that the Viper remote will make the blue led turn on or off.

I am not sure If i picked the right orange and purple wires to tie into?
Do I need to tap into the ignition wires related to the key?
Did I get the right wire for the brake?

The viper install sheet did not answer many of my questions.

I am hoping one of you Pros will look at the pic and see something wrong.

What is the minimum needed to make it start?
Do I need the door wire connected?

I did the hood pin, Tach wire, ground and the wires shown in the photos.
I have not hooked up the door locks as they need new actuators. That will be the next project after the starter works.

RED Wires:
The truck has 2 red wires, both are constant 12v. I tied into one of them.
The Viper has several red wires. I connected the red on, there is a red/black stripe and red/white stripe. Do they need connected? They have fuses, so I am guessing they need connected?

Thank you for any help!!

Anyone have suggestions on why it will not start?

A few things: pins 2 on the heavy gauge harness needs to be connected to power, since it feeds the starter output. The brake wire should be correct, but you should always verify for yourself. You can do this with a multimeter, but a test light will work also.

You need to connect the door trigger, as this will be used for programming. The factory setting (if it's like the older units) is manual transmission, so you may need to change that as well. The parking brake wire may need to be connected and set, too (haven't been an installer for over 15 years, so maybe someone else can chime in).

My ex once told me I have a perfect face for radio.

Thanks geepherder for the info!

Got it to start, now have a problem with the tach wire. That needs to be checked or configured.
Best advice I have for anyone else is to watch more youtube videos on viper equipment.

I never connected the door sensor and the vehicle starts. You need it to turn on/off valet mode, or other setting as mentioned above, so it will be done later.
Parking lights not connected yet.
Grounded the parking brake wire to disable Manual transmission mode.

I connected all of the fused red wires to a SINGLE 12v constant red wire shown in the photos above, you could use both wires, but one was enough for me. To answer my own question, I did not have to cut or mess with the ignition wires (so far). The brake wire in the photos has not been tested at this point.


It is nice to pop the hood to kill the starter (hood pin switch) when having problems during testing. Hood pin was installed between the washer fluid and the head light.

I hope this info helps someone in the future.
