Wilson and Norwood on target as Town make it nine points from nine
New Town boss Paul Cook watched on from the stands as Blues came from behind at 10-man Accrington to make it three successive wins in League One.
Dion Charles opened the scoring at the beginning of an action-packed first half before Seamus Conneely picked up a straight red card, James Norwood seeing the resulting penalty saved by Nathan Baxter in the Accrington goal.
James Wilson and Norwood netted late in the half to complete the turnaround before a battling second-half display against the spirited Reds was enough to secure the points.
Town had the first chance of the game inside two minutes. Andre Dozzell drove through the middle before playing the ball out wide to Alan Judge, with Myles Kenlock overlapping. Troy Parrott couldn't get enough on the left-back's cross however before Norwood's shot fell wide of the mark.
Accrington took the lead just a few minutes later. Paul Smyth's low cross from the right wing was too hot to handle for Tomas Holy and Charles poked into the back of the net from close range.
Town had a golden chance to equalise on 16 minutes as Parrott was brought down in the box when one-on-one with the goalkeeper by Conneely.
Accrington's skipper was sent off for denying a goalscoring opportunity but Baxter guessed right to deny Norwood a leveller from the penalty spot.
The hosts had Baxter to thank for maintaining their lead again with just under half an hour played. Blues were patient in possession before Keanan Bennetts found Norwood with a low ball into the box, the latter turning under pressure from Ben Barclay before seeing his shot from inside the box tipped around the post.
Blues saw claims for a second penalty waved away from the resulting corner as Baxter appeared to come through the back of Parrott before punching clear.
Accy's 'keeper, who had taken a knock in the process, was replaced a few moments later by Toby Savin.
Savin was involved instantly, parrying away Alan Judge's swerving shot from 25 yards after the Irishman had cut in the from left flank.
Town levelled the game with four minutes of the half remaining. Dozzell's in-swinging corner was spilled by Savin at the feet of Wilson, who made no mistake and fired into the back of the net from a couple of yards out.
Norwood twice went close to turning the game on its head in the following two minutes. First, Savin pulled off an impressive reaction stop to deny his effort from inside the box before he was inches away from getting on the end of Kenlock's teasing ball across the face of the goal.
Town continued to ramp up the pressure and got their reward towards the end of six additional minutes after Bennetts was pulled back by Cameron Burgess, the Reds defender picking up a yellow card.
Dozzell's wicked in-swinging delivery from the right wing free-kick was headed past the helpless Savin by Norwood to put Blues in front.
The first chance of the second half fell to Joe Pritchard but his well-hit left-footed half-volley was blocked by Teddy Bishop from the left corner of the box.
Norwood looked to be in on goal again moments later but Michael Nottingham did enough to put the Town striker off before Bishop's involvement continued by being brought down by Charles, who was booked.
Holy, who had largely been a specator since the opening goal, got down well to deny Nottingham's header from Pritchard's free-kick with just under 10 minutes played in the second half.
Town continued to dominate possession against an Accrington side who looked to hit on the counter before second-half substitute Sean McConville was booked for simulation.
Wilson became the first Town player to pick up a yellow card with 11 minutes remaining for a push on Smyth.
Blues could have added a third goal late in stoppage time but Aaron Drinan, having rounded Savin, saw his attempted pull-back to a plethora of supporting players turned behind.
