Margate Boss Nikki Bull brought Danny Fitzsimons into centre half in place of Brett Johnson while the Gate Manager was able to name six substitutes with Marcel Barrington back from international duty and Michael Thalassitis able to return after his hamstring injury.
Margate took the lead on 17 minutes as Adam Cash raced onto a poor back pass from Shaun Preddie allowing Cash to stroke the ball past the on-rushing Luke Williams in the Harrow goal.
Meite, who had spent a week on trial with Premier League Champions Leicester City was causing the Margate back-line some problems and he saw another effort fly over the bar from 25 yards.
Defender Manny Parry almost doubled Margate’s lead on 32 minutes as he forced a good save from Williams before the home side raced down the right hand side and swung a cross in which was parried by Ward straight to the feet of Harry Newman who made no mistake from six yards to level things up on 35 minutes.
The Gate were given the chance to re-take the lead right on half-time as Williams hauled down Alex Osborn when through on goal leaving the referee no option to point to the spot and book the Harrow goalkeeper.
Striker Elliott Buchanan made no mistake from 12 yards scoring his third goal in as many games to give the Blues a 2-1 lead at the break, leaving them just 45 minutes away from their first, first round appearance in 14 years.
The visitors started the second half in quick fashion with Buchanan, Matt Johnson and Daniel Akindayini forcing Williams into saves as they looked to extend their lead. Despite the early second half pressure from the Blues they gradually began to defend deeper allowing the hosts to force opportunities which the Gate kept at bay with Fitzsimons again at the heart of the Blues defence.
Harrow introduced Lewis Driver in the 65th minute and he made an instant impact as he somehow hit the post from six yards out when it looked easier to score. Driver continued to look a threat and he grabbed Harrow’s equaliser on 79 minutes as met a long throw into the box flicking the ball past a stranded Ward.
The game had now turned on its head and Harrow looked the likely winners as Driver again forced an opportunity goalwards before Meite dragged an effort wide of the post in the 90th minute.
Margate had to survive three minutes but almost were dumped out in the final minute as the ball bounced to Webb who somehow managed to blaze open from six yards with the goal wide open.
