old style chip missing knob

[kreepin2g]

i pulled my ecm tonight and found it has a old chip in it( what ive found by googleing the numbers). I found its a 4 position chip with a place for the knob but there is not a knob anywhere to be found. so my question is does anybody know where i can get a knob to plug into it or is it possible. the numbers on the chip are eec_2_1 c/s:4189

there's a fair chance it's a TS chip...I ordered a replacement knob through them, it was around $50

if it's a ts style chip i have a spare switch laying around I'd mail ya for $20. You'd just need the hold down nut and position limiter for it (you can use a paper clip)!
