Took it to the gym again and then dinner, had been hoping to get her on the highway to stretch the legs a little but dinner took so long decided to just go home afterwords
What did you do to your non g-body project today [2025 edition]
- Thread starter 86LK
- Start date
put a new rain cap on my shop chimney.
And i tried to sweep out the shop, but the wind was fighting me the whole way.

Fair question, so, summarily, relays are a kind of electrical switch but instead of the toggle for off/on being mechanical, it is electrical. Internally there are two circuits that interact. The first is a heavy circuit that is normally open or off. The second is lighter; and it is a trigger that when activated, acts to turn heavy circuit on. This actuation allows power to flow through the relay from a direct pure source such as an alternator or a battery without interference. Relays typically appear in circuits for lights and horns and anything else where you don't want the quality or consistency in operation to fluctuate or vary. Old cars were bad for this because they were wired directly to the generator and as it spun faster or slower that lights would get brighter or dimmer.
Innovate, the mfgr of the AFR gauge, wants clean power and continous delivery. The power source for the gauge is going to be the battery. When the van is started, power from the battery will be fed to the O2 sensor and the signal from the sensor will get sent to the gauge for display. The power source that turns the relay on is the primary ignition wire that feeds power to the coil from the key swtich. Key on, power on, sensor active; key off, power off, sensor asleep.
Which actually raises another point. if I want to work on the electrical circuits on the van and not have the O2 sensor hot, I am going to have to install a switch in the sensor feed circuit to allow me to shut it off to protect it. Huh!! From Complicated to Simple and back to complicated again. Bother.

OK so you are using it as I was thinking you ought to. But I would put the switch on either the relay coil power or ground myself.
The ol' Daytona made another appearance today:
The aforementioned 383:
And I pulled the Recaros from the cab to put into the Cutlass. My dog tracked a melting tire plug all over one but they'll be getting dyed black anyway. They're swapped side to side here:
No G Bodies were touched today so it's not a G Body project yet.

Not a bad thought either way. I do plan to tap into the lead from the key switch to the HEI coil pak for continuous power and that half of the wiring is about ready to lay in but the ground lead from the relay has yet to find a home so it is open to being extended and having a toggle switch grafted into it; I even have an orphan hole in the dash that could be repurposed to hold that switch LOL the same switch that it used to have in it in the first place.
