Small button relay (?) driver side kick panel

[rosso]

Can anyone tell me what this little thing is? It is at the driver side kick panel along side the hood release lever. Has two green wires from it to connector, then green/yellow and green after connector. It is on a little bracket  and has the number 204 on it.

 

I started looking at the interior to asses what needs to be done and don't remember ever seeing one of these. Also, I could not find on the interwebs a good wiring diagram with wire colors. Anyone?

I remember one of those in my 521 wiring... I think it was a thermal sensor, but I cant remember what it was wired too....

I could have taken a better photo - here's a diff angle.

Yup. It senses the interior temperature above 50F and combined with up to half throttle and any gear but 4th turns on the retard set of points.

This is mine from a 72 521....

I think have a book in my garage that has the wiring diagram I took this pic from.....

Car colors are differnt, but its the same sensor, if someone else doesnt clarify by tomorrow I'll dig out that book....

Thanks Mike, I remember about the second set of points in the distributor and thought that was all handled by the crazy throttle contraption under the hood.  Since I am going VG33 I may just tuck this sensor up out of the way in the dash and leave it.

The crazy throttle contraption is the throttle position switch. It's on when the throttle is open 45 degrees or less.

Hey Crash,

 

If you have a good copy of the wiring diagram you can send, I would appreciate it. So far online I found one that had the same wiring as the above photo but it was a low quality really fuzzy image and wiring colors were not readable.

 

Thanks,

M

Your profile says you have a 72 510 wagon...

I think I have one book that may have what you want, I'll look tomorrow....

Remove the sensor and jump the plug, I had a problem with that exact sensor in my ka510 and it would shut the whole ecu down with the way it was wired.
