Using two T20 flash units with TTL metering

Hi I'm new here,
Due to a combination of turning 50 , reminiscing, having too much Scrumpy , and going on EBay , I am now the proud owner of an OM2sp ( seems in superb condition) . I want to use it for macro photography ( so I can see how much money I now have left! )
I am struggling on how I can set up lighting . I would love to have two T20 flash guns mounted on a purpose built bracket ( can make myself ) driven via my OM2sp TTL connector . Is that possible and if so how and what do I need ? Really want to try and maintain Fully TTL / OTF metering if I can .
If anyone out there can give me advice I would really appreciate your thoughts ,
thanks , new member Andy .
ps the only advice I can offer is cut up your credit card before drinking a gallon of Scrumpy and then going on EBay .

You would need three TTL flash cords and one TTL Multi-Connector. It is theoretically possible to tie nine T-series flashes together.

Edit: Oh the T-20 does not have a TTL socket if I remember correctly, so you would need to get one of the hot shoe-to-TTL adapters for each flash.

Thanks for the advice Dave , just bought a few bits to see if I can make it work !
