He joined United from local rivals Grimsby Town and celebrated his 21st birthday by helping the club to promotion via the 1999 play-off final at Wembley.
Two years later he was released, he joined Halifax for a year before moving onto Northampton.
He is keen not to add to the three relegations he has already experienced as a first-team player.
He told the Macclesfield Express: "Scunthorpe have been on a slippery slope since Christmas but there's absolutely no doubt at all - I want to get a win for Macclesfield which would see us safe.
"I lived in Scunthorpe up until two years ago and all my family still live there, but I came here to play in the Football League and that's what we can make sure of if we win on Saturday."
A win tomorrow, couple with York losing, would see the Iron pull six points away from the relegation zone with two games to spare.
A defeat, and a surprise win for York at league leaders Doncaster, would see Scunthorpe only out of the relegation zone on goal difference.
United will give a late fitness test to centre-back Andy Butler ahead of tomorrow's match.
If he doesn't pass then winger Cleveland Taylor will come back into the side, with a switch to a 442 formation.
Iron manager Brian Laws has issued a rallying call urging the club's fans to get behind the team.
He said: "The Scunthorpe supporters have a massive part to play.
"They know the consequences if we don't get the results we require.
"Get behind the team and inspire us because you do play a mjaor part and I'm pleading with you to come out and help us."
The Silkmen are expected to welcome back forward Jonathan Parkin to the squad after a knee injury.
Parkin clashed with Iron forward Steve Torpey earlier in the season while he was a York player, receiving a red card for his troubles.
