Hi guys!

I need some help. I have got a 86 vette. I need to replace the air injection crossover tube. When I tried to take the old one out, I have just find a plug, which was unplugged.
Probably stupid question, but I don't know what is that. I didn't find any harness to plug in it. I don't know where it goes. I try to upload a photo. Thanks for the answer

Thermo-time switch for 9th injector. Plugs in next to the ECT sensor in front of intake. Maybe yours is gone.

HI Ray
I checked the thermo time switch and you are right, mine is missing. It looks somebody switched them over . There is the ECT sensor on the left (insted of thermo switch) , which should be on the right. There is an empty hole on the right. I try to upload a photo. Hopefully you can see it.

HI Ray
I checked it and you're right. The thermo time switch is missing. It looks like somebody switched it over, because the ECT is on the left and nothing on the right. So I have to switch them back. True?
I try to upload a photo.
