Greetings.....

Just curious about the subject,,,

Some instrument panel of DD51T carry pickups has no Check Engine Indicator (Vans particularly MATIC-type have). The white socket on the panel, the terminal slot (Slot #1)(Green/white wire for vans), is vacant...

Two Questions herewith:

(1). If panel will be replaced with that with the mentioned indicator, where will the wire be terminated on the engine (or any components) to have the indicator work on pickups?
(2). Is the wiring termination to (?)component (if there is) the same for van or pickups?

Thanks for suggestions.... pics will help....

Greetings! Does your truck have a computer that controls the tranny and motor? if not, what would turn on the light if you installed it?
found this:
The "check engine" light is part of your car's so-called onboard diagnostics (OBD) system. Since the 1980s, computers increasingly have controlled and monitored vehicle performance, regulating such variables as engine speed (RPM), fuel mixture, and ignition timing. In some cars, the computer also tells the automatic transmission when to shift.

When it finds a problem in the electronic-control system that it can't correct, the computer turns on a yellow warning indicator that's labeled "check engine," "service engine soon" or "check powertrain." Or the light may be nothing more than a picture of an engine, known as the International Check Engine Symbol, perhaps with the word "Check."

In addition to turning on the light, the computer stores a "trouble code" in its memory that identifies the source of the problem, such as a malfunctioning sensor or a misfiring engine. The code can be read with an electronic scan tool or a diagnostic computer, standard equipment in auto repair shops. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers.
