Legendary British Touring Car Championship team Triple Eight could be back for this season after being sidelined by Vauxhall after the 2009 season.
"We've got the Vectras here and it's a car we know from the ground up because we built it and we have the expertise to get the maximum from it," said Harrison to Autosport.
The team is likely to be on the grid this year with at least one privately entered Vauxhall Vectra with the new NGTC turbo engine.
"We're talking to some serious parties about the 2010 programme already," said Harrison.
Fabrizio Giovanardi is still without a drive for the 2010 season and could be behind the wheel of the Triple Eight turbo Vectra.
