Hello, I have a new issue.
My dash brake light is stuck on even while in drive. I have depressed the emergency brake and released several times but it doesn't go out. I have checked the fluid level and it is fine. Every once in a GREAT while, it will go out. Today I ran a couple of errands and drove for over an hour and the light stayed on. Any suggestions/thoughts?

Here's another thought. With the lock plate flipped upside-down, nestle the c-cam into its normal position against the lock plate in the same way the parts would be assembled in the column. Does any part of the c-cam brass contact ring touch the lock plate?
Hey, wanted to let you know that I FINALLY worked slowly and carefully looking at each part as they went into place. I placed the locking plate in place (not compressed with retaining clip) and pressed on it several times. No honk. I then moved on to securing the plate in place, No Honk. I put the steering wheel back together piece by piece checking for honk. Once all together, and battery was connected. No Honk!!!!! unless I pressed on horn button. So, the only thing different is the insulator on the c-cam. Something on the other c-cam must have been grounding it? I also changed out the relay, just in case. So, it seems like THAT is fixed. Thank you so much for your time, expertise and pictures. Now, I have another issue that I will be posting in another forum about my brake light.

Yes sir

Thanks for the reminder. I loved your restoration build. Thanks for sharing. I hope to continue on my 2 builds with write ups. Life gets in the way and even though I built my dream shop it is so packed I can't work on either at the moment very easily.
Dang that was a long time ago. I guess Chris's site has stood the test of time. Best Chevy truck site on the web.
Life has a way of getting in the way. I've had 3 cars since I got the truck, one crashed, ones my fav daily driver ever and one is my new project. But the old truck just carrys on. Only been towed twice in 48 years. not a bad record. one for a frozen brake caliper and one for the fuel lines rotted so bad the engine was sucking air.
After I got my 85, I found this site in 2004. Someday I will get around to finishing my frame on restoration. Meanwhile it is sitting out of the elements and last time I checked, no foul odors from varmints. First picture is the day I brought it home. The second was in 2010 after an encounter from a deer. I started collecting parts and soon after I took it out of commision. Someday I will make a post but it will not hold a candle to yours.
Thank you! You'll get it done. You'll have lots of candles just like mine one of these days. I had an edge on mine. I was out of work for 3 or 4 months back then and had the freetime to do all of it at once. that's a rare thing. I'll never get to do that again. That's why my camaro is taking so long to finish. The truck just works. Havent had to do a lot to it in all this time. My big problem now is i have to raise the bed to replace the rubber hoses to the fuel tank. They rotted through after 20 years and are sucking air. Camaro needs just a water pump. I've had the parts for two years but haven't had the time to fix it yet. maybe this year I'll get it done...lol I hope so. I miss driving my fun car. I also have a rebuilt 3.73 rear end to swap in it to replace the 2.73 worn out rear and an aluminum driveshaft as well as a full UMI stage 1 suspension for it. I have everything but life keeps getting in the way. My Daily Driver 2018 Impala Premier keeps me going while I play with the old car and truck. We'll all get everything done one day.

leave 1 of your gas tanks empty, when you walk away from the truck switch to the empty tank

The Oil pressure sending unit is a backup system to the Fuel pump relay. Fuel Pump Power through this switch is also cut if the engine stops running as the oil pressure will drop. This is a good post by Hatzie on the operation of the 87-91 pump dual tank setup: http://forum.73-87chevytrucks.com/smforum/index.php?topic=37007.msg310663#msg310663So are you sending switched voltage to the tan/white wire, which is turning the pump on in Start and Run? AND the Oil Pressure Switch? (note this will keep a pump running all the time) If wired correctly the switch should divert the power from left to right. (see link above) Technically you could run switched power down the "test" lead also and achieve the same, but I would use it to Test the pump with isolated power. Have you checked the wiring after the switch to see if you are getting alternating power Left or Right when the switch is changed? (I forgot to hit post yesterday, sorry)

Since the wipers operate by manipulating ground rather than power, I suspect this is a grounding issue. I would reestablish the ground and/or add a redundant ground strap for the wiper switch.

(I put the link here instead of the copy/paste, and this is a continuation I am move this post to that same one. -Captkaos) I wrote the following thread some tine ago. http://forum.73-87chevytrucks.com/smforum/index.php?topic=39789then I changed the switch and the wiper motor and that fixed thee problem until now. Driving down the road the wipers came on and would not shut off. To get home I unplugged wires 17, 18 and 19, 3 and 4. today I plugged those wires back in and the delay module instantly got hot. unplugged the delay module and tried to put the connectors together but the wipers didn't run. with the switch in the off position I no have power on #4 , 17,18 and 19. my next step will be to separate the delay module to see if I can find a short or another delay module any thoughts?

Thanks Chris. Since the relay uses that short pulse from the ECM to prime and a signal through the oil pressure sending unit, I provided 12v to those inputs since I don't have the ECM to do that. My guess is that's where the problem lies. Would you agree? Since I can't just add a 5 second prime signal, it's 12v continously. Just not sure how to wire the relay. Should I just get a different relay that doesn't need those extra inputs to pass 12v?
