Water Tempature Sender part# needed for 1971 Vega

[427VEGA]

I installed Standard part# TS51 and it is not working,I tested the guage so I was hoping someone has the correct part# thanks.

Many current replacement senders are not accurate with older vintage gauges, they do not have the correct resistance value. This even applies to the GM/ACDelco replacements. I can get you a accurate sender for the stock gauge. However, the TS51 is a dual terminal sender and the correct original one for a 71 Vega has a single button type terminal. Has someone changed the wiring at some point? cjbiagi@yahoo.com

Well,I had no sender to start with,and seeing the dual terminal end on the wire harness,I "assumed" it was the correct sender,do you know a part# that is needed?thanks.

The original GM # is 1513321

OK,THANKS,I WILL INSTALL ONE TODAY AND SEE WERE I'M AT.

Even the 1971 wiring diagram shows two wires going to the sender,when I uplug it I can hear the TCS on the firewall clicking,when I did a test with the one wire sender it does move the gauge but is showing about double the temp,is there something I am missing with the TCS?
