it's on the drivers side under the dash or right around the kick panel area, it's a black plastic square plug that is only connected to wires on one side, there isn't a specific place for them other than that general area. And it's kind of expensive to replace them, if you find it you can take it out and resolder the circuits on it and it should be fine. If you have any questions about what it looks like go buy one and look for the plug that looks just like it.. that's it.

Why would a fuel-injected 1986 Honda Prelude crank but not start when hot?

Supposedly, there is a main relay (located in driver's compartment, under dash?) that gets "distant" when it gets hot. The engine will crank, but that's it. Solution is to replace main relay (Dealer>$70), re-solder every connection in the relay/circuit board to eliminate whatever connection is cracked (& heat spreading), or air out the interior of your car until it is cool enough to fool the main relay . . .
