Need pinout of Rinda ECM 555 adapter (94006)
 

I bought a used rinda diacom cable, but it didn't come with the ECM/PCM 555 adapter - just the MEFI adapter. I'm going to order one, but I'm in a hurry to read my trouble codes (got the 2 beeps/min) tomorrow. I'm planning on making a temporary jumper but want to make sure the mapping I have from the 4-pin DLC connector to the 6-pin rinda connector is correct.

Can someone verify these pin mappings?
