remove the "dot"s and replace with real "." and remove the white-spaces, add your own http and :// if you need to.
it has links to the software, and diagrams of the connectors.
your machine has it's connector on the part of the harness that runs over the bell housing, on the operators right hand side, about where the operators right heel would sit but under the floor pan, look for a 4 wire connector that has what looks like 1 wire looped back into itself. that is the cap for the diagnostic plug.

Thank you for the reply. I do actually have the spectrum leads but the laptop I had with the software on was stolen so they are a little useless unless no can find the software online. I will have a look for the DLC plug and see what codes the machine flashes up.
If I can find the software online where would I find the importance connector? The machine I have the cables etc for was a fgcu70 Toyota with California emission control.

if there are any diagnostic codes stored in the ECM you can retrieve them by using a jumper (if you do not have access to a laptop computer using the spectrum software).

do this:
With the key OFF, connect the diagnostic jumper to the DLC located near the ECM. The jumper will connect diagnostic pins A and D. Turn the ignition ON but do not start the vehicle. The malfunction indicator lamp (MIL) will begin to flash.
The MIL displays three digit codes by flashing the first digit, pausing, then flashing the second digit, pausing, and then flashing the third digit. There will be a long pause between codes. For example, a code 143 would be one flash followed by four flashes followed by three flashes.
The MIL will first display a 166 three times. Code 166 indicates that the ECM based diagnostic routines are functioning. Then, any Diagnostic Trouble Codes stored in memory will display three times each. The MIL will then start over with the code 166. If the vehicle is started while the diagnostic jumper is in place, the MIL will flash rapidly.
Diagnostic Trouble Codes may be cleared from the system ECM memory by moving the ignition key to the OFF position and removing the (F2) system battery fuse for at least 15 seconds.

hope this helps

You've been swooped!

you may want to start a new thread, as this one shows up as looking for info on an h400, and I see now that we are looking at an h40, which many more folks will be familiar with.
AS this is an impco spectrum system, the flash codes can be retrieved, but if you have training and a cable and software for other spectrum systems, then you are a few steps ahead. have you ever worked on a spectrum system?
