obd1 aldl port has ground (A) and data (E) but does not have 12v so just plugging in an SM it still needs 12v , but you could use one of the unused ports to add a pin and supply 12v to it and then pick it up in your aldl plug
ok great thx thats a good option
I might make a plug for the 12v ciggy lighter
I just had an old scanner I could sacrifice the plug but probably easier to just put male spade connectors on the scan masters wires
on the SM i use for testing ii put the power and ground on cig plug and then run the white wire with a pin on end for the data , takes two seconds to hook up

if you have time could you take a pick of your set up so I can fashion mine after it
just checked my ciggy lighter and got 12v there like to see your pin connector for the ALDL tried one I had laying around the shop but it doesn't seem to go in very well
so here is how I did my portable scan master works great and I can take it out when at shows but can always see what is going on with the car, used an old 12V plug for a spot light I don't use anymore
