How do you bypass the courtesy light delay on a 88 Corvette?
Just wondering if I can bypass the courtesy light delay switch rather than go buy a new one.... Any wires that I can reroute to just get the light to go off instantly when the doors are closed?

I think that once you can get to it and pull it toward you, all you have to do is splice all the white wires together. I think there are 3 of them. One single and two that are paired up. You can leave it plugged in, since this will bypass the relay. This is the way it is on my '85, I don't have the FSM for the later years but they might be the same. The only difficulty is getting to the relay since it was behind the breadbox taped to the wiring harness. A tight fit to get to without also dropping the ECM.

There is a simpler way to bypass the relay too. Run a short piece of wire, preferably white and the same gauge as the white wire that is going to the door pin switch between the hinges. Tap into the white wire and run it to the footwell light under the dash. This light also has a white wire going to the lamp, tap into this one with the white wire coming from the door pin switch. This should bypass the relay also. I'm guessing the RH side would be easier to do, but I'm sure it will work if you did it on the LH side. Essentially all the dome light relay is doing is grounding the white wires that go to your interior lights. Since the door pin switch also goes to ground it will do the same thing the relay did. Technically, the door pin switch is a trigger for the relay to ground the white wires going to your interior lights, it's just using a delay timer to hold the circuit to ground until it times out then opens the circuit. Another function of the delay timer is to turn off the interior lights when you turn your ignition key to the run position. If it didn't turn off the interior lights then the delay timer would leave the interior lights on til it timed out. Just some more useless, technical information.

Cut and paste from one of "Hooked On Vettes" great replies. 
If the Courtesy Lamp Delay timer is bad, you can buy a replacement or bypass it. To bypass it at the Courtesy Lamp Delay timer connector, you cut the white wire at Pin A and cut the two white wires at Pin D. Solder the three white wires together. This will cause the courtesy lights to come on when the doors are opened and go out when the doors are closed. There will be no delay time out for the courtesy lights.

I know this is an older thread, but just in case someone is looking at archives
When we were making the delay timer boards we kept getting request for a by-pass board. So we made both. Either board will fit in the factory box and installation only takes a few seconds. This gives the car owner the opportunity to either keep the delay or to by-pass it all together and make the lamps work off the jamb switch.

Another option is to just unplug the board. You can then turn the lights on and off manually at the courtesy light or by turning the headlight switch. You can have the lights when you want them and leave them off when you don't.

The purpose of the bypass board is that you don't have to cut and crimp wires and then you can put it back to stock if you want to. I can see where some people might want to do that.

Can the board go bad and let only work one bulb?
My driver side bulb works with the timer.
My pass side does not gt power, bulb is good, jamb switch is good.
