Programming PIC16F877a using PICKIT3

Question

I'm trying to program a pic16f877a using PICKIT3 and MPLAB without success.
I'm powering the pic with the pickit.
I verified the connections almost 20 times, everythings plugged at the right place , every times when I try to burn the pic I get :
"Too much current has been drawn on VDD. Please disconnect your circuit, check the CLK and DATA lines for shorts and then reconnect." and "target device id (0x0) is an invalid device id. please check your connections to the target device".
I'm using a RC Oscillator with an arduino since the pic does not have an internal oscillator and I don't have any quartz or battery.
I made a quick schematic using paint to show you my connections using an image that I found on another similar thread(How to connect a dsPic30f2010 to pickit3 icsp).

Thanks !

Maybe this? 2.4.4 Debugger Powered The internal debugger power is limited to 30 mA. — Tyler, Jul 19 '17 at 19:08
The PIC16F877A has only two Vdd and two Vss connections. Your diagram is showing three for both. Can you update your schematic with pin numbers? — Glenn W9IQ, Jul 19 '17 at 19:15
I ran into that problem because I had selected a debug header in the project properties (in other words I had erroneously told the development software that I had a debugger adapter board connected). So the software wasn't accessing the PIC correctly because I had no debug adapter board installed. — Entrepreneur, Jul 20 '17 at 03:14
Your schematics show a shot in Vdd and Vss near the C3 decoupling capacitor (100 nF). i also doubt the presence of a shot. — Bhavneet Singh Bajwa, Jul 20 '17 at 06:25

Power the PIC from the same power supply as the Arduino. Remove the Vdd connection to the PIC from the PICKIT3. It may also help to add a 10k resistor from PGM on the PIC to ground. Make sure you have your PICKIT3 set to the correct processor.

You should then be able to program the PIC.
