 In order for the SMEC to be able to be put into programming mode with only 12v, a zener diode on the rear of the board must be bypassed. This is detailed in the pictures to the right. Once you are sure things are correct, it is a good idea to seal everything up with some silicone caulking that you can get at a home improvement store. In order for the SMEC to be able to be put into programming mode with only 12v, a zener diode on the rear of the board must be bypassed.

 If you have a T1 harness and plan on using a charge temp sensor, now would be a good time to add a wire to pin 21 as well. If you have a T1 harness and plan on using a charge temp sensor, now would be a good time to add a wire to pin 21 as well.

- The SBEC Flash Module can be installed either directly to the board, or into a 32-pin socket. For the flash module, we use the ‘extra’ 4 pins that Chrysler was so generous to provide on the SBEC boards. The ‘extra’ 4 pins are just above the 28pins used for the regular SBEC chip (the 87C257) and contain the control signals used for flashing. So, unlike the SMEC, there is no need to point-to-point wiring to get the control signals to the board.+The SBEC Flash Module can be installed either directly to the board, or into a 32-pin socket.

 3 of the 4 ‘extra’ pads were not drilled by Chrysler. One of them usually is. The pin just to the right of pin # 1 is usually drilled and filled with solder. So, a solder sucker can usually clear it out. However, I have found a couple of SBEC’s where this hole was not drilled. 3 of the 4 ‘extra’ pads were not drilled by Chrysler. One of them usually is.
