4wd indicator light switch - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Phuloi68** · 03-18-2004, 07:48 PM

does anyone know where I might be able to find a 4wd indicator light switch for a np205 (part time) transfer case?
The dealer says they are discontinued,Chevy Duty only has them for a 203 or an 208 and I don't see them listed in LMC's catalog. I thought maybe the 208 switch (made by POLLAK) would work but it's different. I have tried to find a POLLAK catalog to see if they offer the correct one and haven't found one.
This switch threads into top of T/C. It has a spring that goes inside the switch. The spade connections (2) on the top are T shaped. This would be for a T/C from mid 70's I think.
Thanks.

I can't help on the switch, but very curious to what year truck this is in. My 72 blazer has a "front axel engage light" and has the 350/205 combo. The light doesn't work, but I haven't ever seen another one. Do you have pictures?

Dan72cst. I don't have a camera to get pictures so I will describe as best I can what I know.
The truck is an 81 but the 350/205 is from an earlier 70's.
On a np203 (full time) the indicator switch mounts into the side of the shift lever. It kind of looks like a brake light switch. It has two male spades, t shaped, for the wire connector that comes from the firewall harness.
The np205 (part time) has a switch that screws into the top of the case. There is a spring that slides into the bottom of the switch. It also has the t-shaped spade connector.
The 208 t/c has a screw in switch also, but it has a ball at the bottom end and the connector is a plug in type.
These switches, when activated by the transfer case in use, send a message to the indicator light on the dash.
This is information I have learned in the last couple of weeks. I hope what I have said is all correct and maybe someone else can help or give pictures.
I also hope someone can help me find one for the 205.

Try six states, I bought a remanufactured 205 from them and it came with a new switch installed. Its worth a shot.

I tried six states (one in spokane) and they said if I could measure the switch maybe they could come up with something. I don't have a switch to go by. I have a switch from a 208 that is similar but the threads are not the same so I don't know about the rest of it. So I'm still looking for someone who has one or can point me in the right direction. Thanks.
