    Engine bay of my 1980 d100.
    I know, it’s not an abody but can someone tell me exactly what these are? Leanburn setup maybe?

    The top pic is the voltage regulator. T THINK the bottom ones control the idle settings

    Fire wall mounted is definitely the voltage regulator.

      The voltage regulator is on the firewall. The two on the fender are emission timers, one was for the EGR and the other is timing delay.

        Hardly an expert, but I don't think "lean burn". I see a Mopar ECU for spark under the steering column. I think "lean burn" was essentially the same "Spark Computer Box" in my 1982 Dodge Aries. That was mounted on the inner fender, but a similar box w/ "Lean Burn" label was mounted on the air cleaner in small-block engines, at least from what I have seen in junkyards (usually bigger cars). This box had a vacuum sensor that looked like a vacuum advance pod on the side. The distributor had no weights or vacuum advance since those adjustments were done in the box via electronics. It had a 3-wire Hall-effect pickup w/ a metal shutter wheel. Replacement spark boxes were pricey. I bought one once, though the problem turned out to be the crappy Molex-type connector they used on the box. Thank god for the later Weatherpack and Metri-pak connectors.
